Plasticizers account for the largest segment of the additives business. A report from Frost & Sullivan, entitled U.S. Plastics Additives, says that the plasticizer market represented 64.3% of total U.S. plastics additives consumption in 1997, and 36.2% of the revenue. The study names plasticizer manufacturer Exxon Chemicals as the market leader in the total additives business in terms of revenues. After plasticizers, the major segments of the U.S. additives market, based on consumption, are heat stabilizers (18.0%) and flame retardants (16.5%). Heat stabilizers accounted for 34.1% of the revenues, while antioxidant and flame retardant market shares based on revenues were 12.5% and 11.9%, respectively.
Product development trends, as reported by the studies, include the designing of new light stabilizer and antioxidant systems to improve the short-term and long-term performance of polyolefins. Also, as a response to environmental concerns, manufacturers have developed reduced-metal and metal-free heat stabilizers for PVC resin and have limited volatile organic compounds. Concern over halogenated flame retardants has led to a search for alternatives, such as nonhalogenated phosphorus compounds, melamines, and various inorganic materials. Both reports say that globalization continues to be a major market force. According to Frost & Sullivan, mergers and acquisitions are common as companies seek to add distribution channels and broaden product lines.

Ameribrom (Dead Sea Bromine Group) is promoting several new flame retardant products. FR-720 [tetrabromobisphenol A bis(2,3 dibromopropyl ether)] contains both aromatic and aliphatic bromine suitable for polyolefin resins and is especially recommended for UL-94 class V-2 polypropylene. It is also applicable in class V-2 polystyrene. The low dosage of FR-720 needed to achieve UL-94 ratings reportedly provides good cost performance and allows the physical properties of the resin to be maintained.
FR-1025M (pentabromobenzyl acrylate) is now listed on the Toxic Substance Control Act inventory and is commercially available. According to the manufacturer, this brominated flame retardant monomer, available in powder form, is unique in being polymerizable via reactive processing on commercial compounding equipment, and it can be reacted in many systems by homopolymerization and copolymerization. Use of FR-1025M via reaction molding in engineering thermoplastics, including PBT, polycarbonate, nylon 6, and nylon 66, allows polymers to reach flammability standard UL94 V-0 while maintaining good mechanical and physical properties. Said to have good thermal stability and excellent shelf-life, this product improves the compatibility of the polymer matrix with the glass reinforcement and acts as a processing aid. It maintains the transparency of such resins as polycarbonate, crystalline polystyrene, and polymethyl methacrylate. When copolymerized with PP, it acts as an adhesion promoter and improves dyeability.
FR-245 (tristribromophenyl cyanurate), another new product, has high FR efficiency and is melt-blendable. Used mainly in ABS and HIPS, it reportedly provides an optimal combination of heat and light stability, impact resistance, and melt flow properties.

Most of the new products introduced by Ampacet over the past year can be classified into three major categories: masterbatch for flexible packaging, masterbatch for protective film, and masterbatch for agricultural film. Ampacer reports that in the area of masterbatches for flexible packaging, it has developed several high-quality white products that eliminate or reduce die build-up in cast film and extrusion coating. Products 110313-B and 110359 are both 70% new generation Ti[O.sub.2] in autoclave-produced LDPE. The first is based in an LDPE with a melt index of 8; the second is based in an LDPE with a melt index of 12. The broader molecular weight distribution of autoclave vs. tubular is said to improve the performance of these products at higher loadings (12% to 25% Ti[O.sub.2]) in thinner gauges at processed at higher temperatures. Product 110438, for extrusion coating, is 80% Ti[O.sub.2] in LDPE with a melt index of 12. This product is free of stearates, as are the two mentioned previously. Product 110025 is 80% Ti[O.sub.2] in LLDPE specifically developed for blown film. Product 110697 is a 60% white masterbatch based in LD/LLDPE and targeted primarily at the European cast and coating markets.
Two new products are the process aids designated as 100706 in Europe and 100458 in the U.S. based in LLDPE with blends of fluoroelastomers and additives, these products are said to offer high resistance to abrasion and reduce die buildup in high-heat applications, such as east film and extrusion coating. Versions with 5% active ingredients are also available.
In order to meet market demands for non-amine-based packaging, Ampacet has developed the following antistats. Products 101140 and 101132 are reported to have superior static decay times and surface resistivity in addition to improved shelf-life. Specifically developed for blown film for electronic packaging, Product 101140 is an improved version of 100320 with better long-term performance at low relative humidity ("Mil Spec" 12% RH) and food contact acceptability up to 16%. Product 101132, which is 10% active, reportedly passes the 12% RH Mil Spec even after three months. The recommended usage for this product is 5% to 8%, and it is acceptable for food contact at all concentrations. As it is stable to 500 [degrees] F, it can be used in cast film applications. Ampacet also offers 6008-PS antistat, which has a 20% active antistat based on high-impact polystyrene. This product is designed for extruded sheet.
Ampacet has also developed laser marking masterbatches for use in flexible packaging. Intended for polyethylene and polystyrene, Products 101183 and 101186 (European codes) are said to offer permanency and require no surface treatment while avoiding mechanical wear and harmful ecological effects. The American versions are 101285 for clear film applications, and 101286 for opaque or pigmented film.
In the category of antifogs, the company has developed Product 101082, which can be used at half the level of conventional blends. High use levels are said to interfere with print quality and sealability. Ampacet recommends that the new product be used at 5% to 7% to yield approximately 5000 ppm active ingredient. Product 101082 is reportedly based on FDA-acceptable glycerol/ester chemistry and is suitable for high-heat processing, i.e., cast and coating. The carrier, a blend of LDPE and LLDPE, has no inorganics and thus shows low haze. A suggested application is fresh-cut produce packaging.
Two biocides have also been introduced during this time period. Product 101174, called Biostab 74, was developed by Ampacet Europe. Containing 7% of a low melting (57 [degrees] C) off-white organic pigment, it is recommended for transparent applications (2% to 3% in PE and 3% to 7% in PP). Product 101144 contains 15% of a proprietary nonmigrating inorganic material. According to the manufacturer, when tested by an outside lab, both LDPE film and HDPE chips showed either no or less than 10% growth of fungal or bacterial organisms. The additive is said to be unaffected by solvents and have little or no volatility and hence no odor at normal plastics processing temperatures.
The company has also designed "super antioxidants" - products 101124 and 101125 - which reportedly help alleviate the discoloration commonly associated with over-oxidation of phenolic antioxidants. Suggested usage is 2.5%. For applications that cannot tolerate the addition of stearates, stearate-free Product 101124 is recommended.
Ampacet is promoting several masterbatches for the coloring of protective film. Products used in this application must be able to avoid interaction with the adhesive that laminates the film to the substrate. Also, no gels can be introduced during processing, as these can mar the surface. Three products now offered for protective film have been in use for years but have recently been modified for this new application. Product 11495-8 was a 50% photographic-coating-grade white, and Products 11151-T and 11989-I are improved versions of Ampacet's 50% Ti[O.sub.2] products. A recently developed product is 110786, which contains 60% Ti[O.sub.2], in a new formulation said to be "whiter/brighter" than the conventional Ti[O.sub.2]. Product 110850, developed for use in protective film for cars during shipping from factory to dealers, reportedly combines a state-of-the art surface-modified weatherable grade of Ti[O.sub.2] with a cost-effective HALS in a PP carrier.
Also new from Ampacer are Products 400700-B/400700-D. Both products are intended to create a matte finish or reduce gloss in multilayer BOPP, CPP, or CPE for such applications as paper and printing lamination and adhesive tapes for use in photo albums.
The company has also introduced high-performance masterbatches - Products 190340-A and 190340-D - for use in developing more effective thin-gauge mulch film and other agricultural film structures. Both products contain N-550-type carbon black in a higher alpha olefin (HAO) linear low-density polyethylene. Product 190340-A is 45% loaded; product 190340-D is 50%. The loading and flow properties of 190340-A are said to make it ideally suited for use at high loadings of carbon black (8-10%) at very thin gauges ([less than]0.7 mil). Product 190340-D was specifically developed to be a high performing, cost effective product for geomembrane sheeting, and its flow properties are said to allow good incorporation relative to products previously used. The HAO carrier in both products reportedly offers enhanced performance because of the improved compatibility with the resins commonly used for geomembranes.
Other masterbatches for mulch film are Products 190580 and 190660, both of which contain 40% of an N-550-type carbon black modified to yield improved flow properties. Product 190580 contains an NR-type HALS; Product 190660 contains an NOR-type HALS. Both HALS are said to have better pesticide resistance than the conventional HALS. Each masterbatch has been run at 20% (8% carbon black) at less than 0.8 mil Recommended use levels are 15% at 0.8 to 1.0 mil and 12.5% at 1 to 1.25 mil.
Two new whites have also been introduced for mulch film. Products 110844 and 110880, for either monolayer or coex over black, consist of 70% Ti[O.sub.2] in an easy-to-process weatherable grade. Product 110884 contains an NR-type HALS, and Product 110880, an NOR-type HALS. The nonstabilized version of these products is 110607. Ampacet reports successful trials of these products at 20% usage (14% Ti[O.sub.2]) in both blown and cast 1.25 mil film. The company has also developed Product 12203 for driver mulches, which have been shown to reduce the white fly/aphid population around plants and increase crop yield. The product contains an NOR-type HALS and is recommended for use at 7% in 1.25 mil film.
Additional new products for agricultural film include 101248, a highly loaded product with a 20% NR-type HALS in LDPE, and 12222 silver mulch, which contains an NR-type HALS and is recommended for usage at 7% in 1.25 mil film. Three thermic brown IR/UV PE masterbatches are U.S. Product 180480, which contains an NR-type HALS, and European Products 180390-A (stabilized) and 180442 (unstabilized). Reportedly providing improved opacity, these products also offer an advantage over black mulch film in that the soil can be heated during the day. These products can also be used in combination with UV stabilizers. Ampacet also reports that the following codes are in their second year of testing at a major U.S. university: 150525 red mulch (10% usage), 160795 blue mulch (10% usage), and 130272 yellow mulch (10% usage).
Ampacet Europe has developed four photoluminescent concentrates under the Lumi trade name. These concentrates, which absorb light energy and re-emit it as light in dark atmospheres, are said offer high heat stability (resisting temperatures above 300 [degrees] C), excellent chemical resistance, and good hysteresis (enabling them to be charged and recharged many times without losing the ability to re-emit light). According to the manufacturer, they retain their luminescence for several hours without re-exposure to a light source. In addition, Lumi concentrates are nontoxic and nonradioactive. Applications that can benefit from the use of these concentrates include safety clothing, highway signage, traffic markers, roadside worker protection devices automotive dashboards, and electrical appliances. The four grades currently available are Lumi PE MB-12146 for polyethylene, Lumi PP MB-12220 for polypropylene, Lumi PS MB-6200-PS for polystyrene, and Lumi CO MB-12218 for polyamides and other engineering materials. These concentrates are said to be suitable for any resin processing method.
Another area of product development is heavy metal replacements. According to Ampacet, finding a cost-effective replacement has always been a challenge. However, with the recent development of two relatively low-cost organic pigments, PY62 and PY205, masterbatch producers have been able to move in the direction of more cost-effect formulations. Product 130226 represents one of Ampacet's attempts in this area.
In June 1998, the company announced that it will add 175 million lbs to its global masterbatch capacity, which will bring its total capacity to more than 575 million lbs per yr. This increase includes the recent acquisition of Baron Colour Concentrates Ltd. of Kitchener, Ontario, Canada, which provides Ampacet with new production facilities in Canada in addition to a U,S, plant. Ampacet Europe's expansions at its Messancy, Belgium, and Telgate, Italy, plants will also contribute to the announced increase in global capacity. A new production line for highly dispersed black masterbatches will reportedly increase the capacity in Messancy by 20,000 metric tons and Ampacet Europe's capacity to more than 70,000 tons. Ampacet Europe's facility in Telgate, Italy, which produces master-batches and engineering polymer compounds, will expand its capacity in 1999 from 7000 metric tons to 12,000 metric tons, And a joint venture agreement formed in October 1998 with Biblos Color S.A. of Argentina will also contribute to Ampacet's worldwide expansion in capacity. The new partnership, known as Ampacet de Argentina, is said to place Ampacet in a strong position for continued growth in South America's MERCOSUR countries, Ampacet has also announced that it has filed an application for a 100%owned manufacturing facility in Thailand.

AXEL PLASTICS RESEARCH LABORATORIES
A new liquid additive, MoldWiz INT-PUL24 is reported to improve pultrusion processing. The manufacturer says that it optimizes line speed by reducing pull force, while contributing to minimum die wear. This product yields more consistent, cleaner profiles, and will not interfere with bonding or other secondary processes. With a pH of 4.5, INT-PUL24 is much less likely than other products to corrode die surfaces. Also, it will also reduce the viscosity of resin baths, making it possible to achieve excellent wetting of fiber rovings without the addition of excessive amounts of styrene to increase VOCs.
Axel is now offering MoldWiz internal lubricants in pellet form. Available in several resin-specific proprietary formulations, the pellets contain no binders or fillers to contaminate the resin. They are also said to be highly effective at additive rates as low as 0.25% based on resin weight. The pellets can be dry tumbled, gravitationally mixed, or fed directly at the throat or with other additives.
MoldWiz INT-52EPR is a proprietary rubber additive that generally improves flow characteristics and reduces tack, making it easier to process natural and synthetic rubbers, particularly EPDM, TPO, and elastomeric copolymers. In addition, INT-52EPR contributes to easier; cleaner release of cured parts, reducing or eliminating the application of external release agents, and lowering the incidence of mold fouling. Axel reports that customer evaluations have indicated no adverse effect on secondary operations, such as bonding, and no deleterious effect on physical properties of the cured elastomers, even after prolonged storage. Some users have reported an increase in elongation and greater tensile strength when the product was used in various rubber recipes.
Axel has also introduced XTEND semipermanent mold releases. Applications include fiberglass composites for recreational products, RTM for auto products, and epoxy for aircraft components. XTEND release proprietary chemistry is available in water-based and solvent-based formulations, offering processors options for all types of resins and rubber and for all types of molding operations occurring at temperatures ranging from ambient to 1000 [degrees] F. These release agents are reactive resin solutions designed to crosslink and cure on the mold, providing an inert and durable release surface that does not transfer to the molded part. A four-page selector guide is available to help users choose the specific XTEND product desired.
The company also offers MoldWiz EM1212SF2, a water-based external mold release designed to replace solvent-based releases in tough SMC/BMC and other highly filled resin molding applications. The nonflammable product is an emulsion that contains fluoropolymers, phosphate esters, and fatty acids, and is enriched with a small percentage of alcohols to speed drying. According to the manufacturer, it is effective at releasing polyester, epoxy, melamine, and phenolic. The fluoropolymer component is said to provide excellent heat resistance with minimal transfer of the mold release to the final product. Multiple releases from a single application can contribute to reduced manufacturing costs and reportedly enhance mold maintenance. The small fraction of alcohol provides a quick drying formula, which is also nonflammable. And the overall composition is much more environmentally friendly than solvent-based external mold releases. EM-1212 is a special formulation of this product that has been developed for rubber.

In October 1997, Ciba Specialty Chemicals announced its purchase of the additive preblend business of Mallinckrodt, St. Louis. The business acquired has become part of Additives Services, a new unit within Ciba Specialty Chemicals' Polymer Additives Business Unit that will solve problems associated with incorporating a wide range of additives into plastics.
Also in autumn 1997, Ciba Additives opened its Asia-Pacific Technical Centre in Jurong, Singapore. More than US$4 million has been invested in the facility, which provides analytical, testing, and formulation development services for the polymer industry. In November 1997, Ciba Specialty Chemicals opened a new antioxidant and phosphite production plant in Shanghai. The plant is a joint venture - Shanghai Ciba Gao-Qiao Chemical Co. Ltd. - between Ciba Specialty Chemicals, Shanghai Gao-Qiao Petrochemical Corp., and Nippon Alkyl Phenol Co. Ltd. Ciba has approximately a 70% ownership in the joint venture. The total investment for all phases of this facility approaches USS 90 million, and the production capacity is around 10,000 metric tons.
In the first half of 1998, the Additives Division announced that all its standard products will be certified according to a single set of global specifications, regardless of where they are made. While production processes and test methods remain the same, specification limits (now known as requirements) have been improved to reflect Ciba's current global manufacturing capability.
Ciba Specialty Chemicals has appointed Witco Corp. worldwide distributor of its antioxidants, light stabilizers, and optical brighteners to the PVC industry. The distributorship became effective in the NAFTA region and in Europe as of August 1,1998, and is now being expanded to the rest of the world. Ciba has also acquired Witco's Kemamine antistat business for non-PVC applications. Witco's antistats will complement Ciba's newly developed Irgastat permanent antistatic agents. The cooperation between the two companies will also include joint R&D projects in the PVC field. In addition, Witco and Ciba recently concluded a swap of Witcos epoxy systems and adhesives business and Ciba's PVC heat stabilizer business.
In April 1998, Ciba Specialty Chemicals and Roquette Freres, of Lille, France, signed a cooperation agreement for sorbitol-based clarifying and nucleating agents for polypropylene. Ciba will distribute the products previously developed and sold by Roquette under the trade name Disorbene and will integrate these products into its product range under the trade name Irgaclear. The nucleating activity of these products is said to result in the formation of spherulites that are less than 1 micron in size, while the spherulites of nonclarified PP are larger than 20 microns. The reduction in size of the spherulites results in superior transparency and rigidity and reduced haze of the material Also, higher recrystallization temperature leads to shorter processing times and thus higher throughput for the converter There are currently two products in the group: Irgaclear D, recommended for use in thin-walled applications and films, and Irgaclear DM, for thick-walled applications. Approved for use in food packaging; the Irgaclear products can also be used to clarify such medical devices as syringes.
The Additives Division of Ciba Specialty Chemicals has developed a new photoinitiator based on its bisacyl phosphine oxide technology. Irgacure 819 reportedly offers excellent curing properties, along with a photobleaching effect that prevents yellowing in substrates. It is said to be especially suitable for white pigmented formulations and the curing of glass-fiber-reinforced polyester styrene systems. The curing of unsaturated polyester/styrene resins is conventionally initiated by free radicals generated from peroxides. However, this method has several limitations, including high styrene emission during the thermal treatment, limited shelf-life stability of the peroxide-containing formulation, and a limited time/temperature range available to apply the activated formulations. Irgacure 819 avoids these limitations. Applications for this product include wood (furniture) coatings, screen printing; electronics, and fibor-optics. Because of its thick-section curing abilities, a potential application is UV-cured composite materials.
The Prostab tar inhibitor/retarder system has been introduced as flagship products of the Additives Divisions process chemicals business. The product line reportedly works well in butadiene, isoprene, acrylate chlorinated olefins, and other petrochemical streams. Use of Prostab eliminates the need for dinitrophenol and dinitrocresol products, which are said to be somewhat effective in controlling tar but require stringent regulatory reporting in the U.S. and elsewhere.
HP-136, the lactone-based processing stabilizer component of Ciba's Irganox HP, has received FDA clearance for use in food contact applications in polypropylene and polyethylene. HP-136 has also been reared for polyolefin applications by regulatory agencies in Germany, France, and Belgium, and is listed by JHOSPA in Japan. Irganox HP reportedly improves productivity by enabling processing at higher temperatures (above 300 [degrees] C) than would be possible with conventional antioxidant systems.
Also new from the Additives Division is CGL-2020, a high-molecular-weight, high-performance HALS. Said to provide excellent UV stability and long-term thermal stability, the product demonstrates the same low levels of pigment interaction and polymer melt flow interaction that are seen with Chimassorb 119 but at a more economical price.
Irganox 1141 is a new liquid antioxidant for emulsion ABS, MBS, and PVC that has received U.S. and European government approval for indirect food contact applications. According to Ciba, it provides excellent processing stability during the drying and compounding of ABS and MBS, in addition to good color retention. Since it is a liquid, it can be easily emulsified - and the antioxidant emulsions formed have excellent storage stability. Irganox 1141 is also reported to be a highly efficient chain terminator for PVC polymerization. It provides good initial color to the PVC resin and imparts good thermal stability to the PVC compounds. It has the additional benefit of neutralizing catalyst residues and reducing polymer buildup during the stripping operations.
In January 1998, the pigments Division of Ciba Specialty Chemicals announced its registration under the ISO 14001 International Environmental Management System. As of September 1, 1998, Ciba Specialty Chemicals' Pigments and Textile Dyes divisions have been combined to form the Colors Division.
Over the past year, numerous expansions in the Pigments (now Colors) Division have occurred. At the end of 1997, an 18,000 [ft.sup.2] R&D laboratory complex was opened in Newport, Del, Research in the new labs centers on developing pigments for coatings, plastics, inks, and fibers, especially those based on quinacridone and diketo-pyrrolopyrole chemistries; enhancing the performance properties of existing pigments; and improving synthesis routes and manufacturing processes. In addition, attention has been directed at developing "effect pigments" - i.e, those displaying metallic and other special qualities - and lessening the environmental impact of pigment manufacturing.
Also toward the end of 1997, Ciba opened its joint venture pigment plant at Qingdao, Shangdong Province, People's Republic of China. The factory is a joint venture, Qingdao Ciba Pigments, between Ciba Specialty Chemicals (majority partner) and Qingdao Dyestuffs Factory. Another joint venture between these partners - to make textile dyes - is in the development stage. The Qingdao facility will make azo pigments for the coloration of inks, paints, plastics, and synthetic fibers.
In July 1998, Ciba Specialty Chemicals signed a contract with Xiangtan Chemical Industry Research and Design Institute (XCRI) for its second pigment joint venture in China. Ciba will have a 49% ownership in the new company - Xiangtan Chemicals and Pigments Co., Ltd. (XCP) - with the rest held by XCRI. XCP, to be located in Xiangtan, Hunan Province, will manufacture mainly quinacridone organic pigments, which are used for the coloration of paints, inks, plastics, and synthetic fibers.
The Colors Division of Ciba has also recently begun construction of an $80 million facility in Newport, Del., that will produce quinacridone pigments. And in July 1998, Ciba opened its new Pigment Granule Manufacturing Unit (GMU) in Paisley, Scotland. The GMU process creates a new pigment format that will replace presscake pigments for inkmakers, offering environmental advantages, reduction in process cycle time, and easier product handling.

Clariant Masterbatches Division, one of six divisions created from the 1997 merger of the Specialty Chemicals Group of Hoechst AG and Clariant Ltd., has acquired Poly Colors, Auburn, Maine. A supplier of custom masterbatches and compounds, Poly Colors serves customers based throughout the Eastern Seaboard of the U.S.
The Masterbatches Division has announced that the consolidation of Clariant's 13 North American masterbatch production sites is now complete, resulting in several new developments in specialty color and additive concentrates.
One new product is an anodized aluminum-look color masterbatch series for packaging applications using high-density polyethylene. Available in a wide range of colors and custom formulations, the series is said to be ideal for applications that require the high reflectivity, chroma, and luster typically associated with aluminum. Opacity levels can be adjusted from translucent to opaque, and in situations where it is necessary to incorporate more than one material into the layer structure of a container, the color masterbatch can be tailored for low-density polyethylene and polypropylene.
Metallic-effect color masterbatches for automobile manufacturers are also newly available. Applicable for all translucent and transparent thermoplastic resins typically used in injection molding, blow molding, and extrusion applications, this series reportedly contains no solvents or pigments with heavy metals, shows less contrast or visibility when scratched, and offers UV protection. These metallic-effect color masterbatches can also be used for electrical, packaging, sports and leisure, and sanitary and bath applications.
The division has also introduced a new line of custom colors for appliance manufacturers. Formulated for use with natural PP and ABS to replace precolored resin for injection molded parts, this series is said to speed up processing while maintaining the required physical performance and high color tolerance of the components. Clariant has also developed a nonmarking black masterbatch for parts molded from HIPS. According to Clariant, the advantages of using masterbatches plus natural resin vs. precolor include diminished chance of obsolescence and reduced inventory and storage costs in addition to improved delivery lead-time.
Clariant Masterbatches has also introduced new color laser marking packages that will be useful in situations where products require expiration dates, lot numbers, etc. The system incorporates a base resin and specific concentrate carrier, pigment for coloring, and a custom-designed additive package necessary to focus laser energy. This combination reportedly provides integration with a wide range of aromatic and aliphatic polymers.
Another area of product development is antistats. For electronic packaging and other applications requiring fast static decay properties, the company offers a series of amine-free antistat concentrates with various PE and PP carriers and loading levels: AEX 9048A, AEX 9020A, and APX 90192A. Antistat CSX 9018A and CAX 9045A are highly loaded concentrates for PS and ABS, respectively, that meet FDA requirements. Antistats 191126/07 and 08 are said to withstand the high processing temperatures used for PET and PETG. APX 9038A has been designed for biaxially oriented PP film (BOPP) applications, providing antistat and antiblock effects.
Clariant is also promoting new UV light and heat stabilizers. In addition to highly loaded HALS formulations for polyolefins (e.g., APX 9028A for PP), the Masterbatches Division offers formulations for engineering thermoplastics that will result in greater stability and less yellowing: UV40431 is mainly for PBT optical fiber; ATB 9018A is a developmental absorber system for PET fiber; 191680/01 contains a high-performance UV stabilizer for thin-wall PET applications; 00066724 is designed for ABS; and ANA 9007 is for nylon. In addition, the division reports the development of an inorganic, cost-efficient heat stabilizer. PA2HSC200-1, for a wide range of nylon applications.
New flame retardant concentrate are also available. AEX 9046A, which is based on nonhalogen ingredients, has been designed to meet UL94 V-0 specifications. Grade CEX 9049A is a highly loaded brominated diphenylether-free concentrate meeting UL94 V-0 specifications at a 20% addition level.
Clariant Pigments reports that several changes have taken place as a result of the 1997 merger of the pigments business units of Hoechst Celanese and Clariant, which followed Hoechst's acquisition of the product line of Cookson Pigments. Clariant Pigments has increased by 50% the amount of money spent on R&D, and classical pigment production plants are being opened in Asia.
New product developments have focused on the easily dispersible grades of quinacridone pigments. In 1998, PV Fast Violet ER, a very blue shade Pigment Violet 19, was introduced. This followed the introduction of PV Fast Pink E, a Pigment Red 122. Easily dispersible quinacridones are said to find applications in many areas of the plastics industry, particularly in thin-walled articles or in low-shear processing equipment, where their rapid color development saves cost.
Two azo condensation pigments have been added to the product range. PV Fast Scarlet 4RF (Pigment Red 242) is a high-heat-stable, high-lightfast pigment, said to be economically advantageous in various applications. PV Fast Red 2BN (Pigment Red 262) is a rubine pigment with similar properties.
The Clariant Additives Business Unit has also introduced many new products. Hostavin N-30 is a hindered amine light stabilizer that reportedly exhibits low alkalinity, low sensitivity with reactive chemicals, and low interaction with co-additives. This material also shows very good color stability and has potential as an antioxidant. Hostanox 03 is a primary antioxidant that has resistance to extraction. Additionally, the product is said to have very good color retention in contact with aqueous systems. Nylostab S-EED is a multifunctional additive for polyamide that provides improved melt processing, enhanced long-term heat- and photostability, and enhanced dyeability.

Color-Chem has recently commercialized two new dyes, Amaplast Red BSR and Amaplast Yellow LMP. The first is a strong, bright blue-shade red suitable for coloring all engineering resins except polyamide. Reportedly an economical replacement for quinacridone reds, as it is twice as strong at nearly the same price, Red BSR also provides superior heat stability and easier dispersion than a quinacridone. Amaplast Yellow LMP is a bright, strong neutral yellow suitable for all engineering resins except polyamide. Most important, it can be used in place of typical UV stabilizers, such as a HALS or UV absorber, at loadings of 0.01%.
Color-Chem recommends many of its colorants for food contact applications. Further, the company has added laboratory equipment to expedite FDA compliant extraction testing and self-certification of colorants for food contact applications.

The company has developed metallic and pearlescent color formulations for polyolefins that reportedly do not cause any accumulation of large particles around hot runner tips during injection molding. Because of their large size and platelet-like structure, pearlescent and metallic pigments tend to build up around the tips, gradually restricting material flow into the cavities. This situation leads to vestige and high gates in molded parts and eventually requires shutdown of the equipment for cleaning the tips. Color Technology says that the new products can reduce or eliminate equipment downtime and produce parts without high gates or other dimensional nonconformities. These formulations are available in any custom-matched color Color Technology, Inc., 125 Flanders Rd., Westboro, MA 01581; (508) 366-9611; fax (508) 898-9290.

This product reportedly offers low odor and a high-gloss finish. Dexter Polymer Systems, One Dexter Dr, Seabrook, NH 03874; (603) 474-5541; fax (603) 474-5545; website: www.frekote.com
The company has introduced two new silicone additives in dry masterbatch pellet form. Designed for use in acetal systems, Dow Coming MB40-006 silicone masterbatch is a 40% dispersion of an ultra-high molecular weight silicone in an acetal copolymer The carrier resin used in the new product is Celcon M270 acetal copolymer from Ticona with a melt flow index of 27. According to Dow Corning, the new additive provides a variety of process benefits and surface modification characteristics, and a broader range of performance capabilities than silicone additives with lower molecular weights. At levels of 0.5% to 2.5% (0.2% to 1.0% silicone) in acetal systems, the product reportedly offers improved processing and resin flow characteristics, such as faster throughput; better mold filling, internal lubrication and mold release; and reduced extruder torque and molded part warpage. At higher levels, 2.5% to 12.5% (1.0% to 5.0% silicone), the new product can enhance the surface properties of acetal products, such as plastic gears, pulleys, bushings, and window or refrigerator guides. Designed to lower the coefficient of friction, the new additive increases abrasion and wear resistance in these applications. The pelletized form of the new concentrate allows it to be blended with virgin or compounded acetal resin pellets in order to attain the desired silicone level. No specialized equipment is required, and pellets can be added during compounding in either single- or twin-screw extruders or at the feed hopper during injection molding or extrusion.
Another new additive also available in a dry masterbatch pellet form, Dow Coming MB50-008 Silicone Masterbatch, has been designed for use in a range of styrene-based resin systems. The new product is a 50% dispersion of an ultra-high molecular weight silicone in styrene-acrylonitrile (SAN) resin. The carrier resin, Tyril 100 SAN from Dow Chemical, has a melt flow index of 8. At masterbatch concentrate levels of 0.2% to 2.0% (0.1% to 1.0% silicone) in styrene-based resin systems, the product is said to offer the same improved processing and resin flow characteristic as the above-mentioned product provides at similar levels. At higher levels, 2.0% to 10% (1.0% to 5.0% silicone), Dow Corning MB50-008 silicone masterbatch can reportedly provide improved surface properties in SAN, acrylonitrile-butadiene-styrene, and other styrenic resins. Designed to enhance lubricity, and slip and abrasion resistance, and substantially reduce coefficient of friction, the product is meets U.S. FDA regulations for use as a slip-release agent in the manufacture of food-contact film and articles. Dow Corning Corp., EO. Box 1593, Midland, MI 48641-1593; (517) 496-6000.
DSM has announced that it is operating a pilot installation for the commercial production and supply of Stamypor. This new family of highly porous ([greater than] 50 vol%) polyolefin granules is targeted toward applications in the masterbatch and additives industries. The carrier beads for liquid or low-melting additives and reactants are said to simplify the production of highly concentrated nonextruded masterbatches. The base polymer currently used for Stamypor is DSM's low-density polyethylene, Stamylan LD, with a melt flow index of 2.5 dg/min. Stamypor's void content is easily accessible for liquid or low-melting additives and reactants. A polypropylene-based Stamypor grade - with a porosity of [greater than] 60 vol% - is under development and is expected to become available for sampling by the end of 1998.
According to the manufacturer, Stamypor is successfully used for the production of concentrated masterbatches containing antistatic agents, anticondensation agents, slip agents, mold release agents, lubricants, antioxidants, UV stabilizers, EPDM additives, polyisobutylene, and pigments. DSM says that the highly concentrated masterbatches based on Stamypor provide for the free-flowing introduction of liquid additives or reactants into the polymer while avoiding slipping problems during extrusion.

A new aqueous dispersion grade of PTFE fluoroadditive, Zonyl TE-5070AN, has been introduced by DuPont. Like its companion grade in powder form, Zonyt TE-5069AN, the new aqueous dispersion grade imparts lubricity and release properties. Both fluoroadditives are designed to improve processability in paints, waxes, finishes, plastics, and elastomers. The very fine particle size and ultra-low molecular weight of these resins assist the migration of particles to the surface of coatings and other formulations and also inhibit the packing of fluoroadditives in tight clearances.
The new fluoroadditive contains no acid end-groups and therefore is inert to virtually all chemicals, eliminating potential incompatibility with other blend components. The extremely small primary size (0.07 mm average) allows excellent dispersibility and clarity in other materials. The dispersion contains approximately 53 wt% solids, has a viscosity at room temperature of about 25 cps, and has an approximate pH of 10.
A very new product from DuPont is Zonyl TE 6504, which has a higher molecular weight than other Zonyl fluoroadditives and is therefore more resistant to high temperatures. The new additive reduces mold plateout and can increase wear life and lubricity for such parts as bearings, gears, and seals.
DuPont has also introduced liquid Vazo, a free-radical initiator used in bulk, solution, and suspension polymerizations for the manufacture of high-performance coatings and specialty polymer resins. According to the manufacturer, one advantage over the solid form is that liquid Vazo, reportedly the only commercially available liquid azo, is a 100% active ingredient product that can be pumped or distributed by an automated delivery system for better control and precision. Also, in using a liquid azo, manufacturers can minimize exposure to dangerous chemical dust. They may also achieve higher yields through improved solubility, decrease cycle times by eliminating the dissolution step, and reduce total costs by improving process efficiency and lowering labor requirements.

Eckart, headquartered in Furth, Germany, has acquired the aluminum pigment plant of Reynolds Metal Co., Loisville, Ky. The operation is now called Eckart Aluminum L.E In addition, the company has changed the name of its Painesville, Ohio, operation from Obron Atlantic Corp. to Eckart America L.P.
Eckart America has introduced two assortments of aluminum pigments, Mastercolor and Mastersafe. Both are said to offer improved brightness and also eliminate or substantially reduce flow lines in injection molded parts. Mastersafe pellets are 80% to 90% aluminum concentrates. Particle sizes range from 60 to 330 [Mu]. The larger the aluminum particles, the more the flowlines are reduced. Also, the company reports that narrowing the particle size distribution results in much brighter shades. Available in either pellet or paste form, these pigments give plastic parts a very metal-like appearance. High heat resistance allows the series to be compatible with engineering resins, in addition to most other major plastic resins.
Mastercolor pigments, available in gold, blue, and green, are made from FDA-approved material. Because of their large particle size distribution, 125 [Mu] these pigments also display few or no flow lines-and, as in the Mastersafe series, the narrow particle size distribution results in improved brightness. In addition, they are said to offer excellent heat stability and lightfastness. Further, a durable colorant deposited directly on the aluminum flake reportedly permits unique styling possibilities, particularly in combination with other colorants in polystyrene or polyolefins.
Eckart has produced a new color card, "Eckart Metallic Pigments for Plastics," which presents a full line of metallic colors in plastic chip samples, and includes technical and product information. Eckart America L.E, PO. Box 747, Painesville, OH 44077; (800) 556-1111; fax (440) 354-6624.
Eeonyx Corp. is a developer, supplier, and licenser of advanced polymer-based technologies, which include specialized intrinsically conductive polymers (ICPs). The company has introduced a new conductive additive, known as Eeonomer Prepared via in-situ polymerization and deposition of ICPs into a carbon black or other matrix, this product reportedly can be processed into the majority of plastics and plastic blends without degradation or loss of conductivity. The manufacturer says that Eeonomer possesses greater thermal-oxidative stability than ICPs (up to 300 [degrees] C) and that the malt processing of Eeonomer into a variety of plastics leads to conductive blends with improved electrical, mechanical, and melt flow properties, in addition to greatly reduced compounding difficulties and easier end-product fabrication.
It is reported that in certain plastic systems, loading with an amount of Eeonomer half that of a typical carbon black will achieve the same conductivity level. The manufacturer also says that because of improved compatibility, Eeonomer plastic compounds show reduced sloughing when compared with carbon-black-loaded compounds. Moreover, when this product is loaded to heterogeneous plastic alloys, such as TPOs, the result is at least a tenfold increase in conductivity compared with alloys loaded at the same level with high-structure carbon black. Also, it is said that Eeonomer added into silver-loaded thermoset adhesives leads to improved thermal and electrical conductivity.
Eeonyx says that it is very difficult to make carbon-black-based compounds with consistent resistivity in the antistatic to static dissipative range because the required loadings lie on the vertical part of the percolation curve. The company reports that a newer, specially designed class of Eeonomer allows one to fine-tune the resistivity of the product to the desired levels.

A new additive series, Grilon master-hatches, has been developed for polyamide foils. One benefit of the new formulations is increased productivity - because of a faster crystallization and a high antiblocking effect, the tendency toward stickiness during the manufacturing process is reduced. Also, foils with improved antifriction properties are produced. At the same time, the coefficient of friction between the foil and the steal is reduced. According to the manufacturer; these advantages can be achieved without losses of other properties, as Grilon masterbatches are based on PA 6 or copolyamides. In addition, most of the series is authorized for direct contact with food. Ems-Chemie, Domat/Ems, Switzerland; fax +41 81 632 7463.

A product very recently introduced is Engeltone 1115 pigment, a blue-shade red that occupies a new color space for azo pigments used in plastics and powder coatings. According to the manufacturer; tests show that the new pigment complies with FDA extractable limits for food contact. It is also comparable in heat stability to many high-performance, bright reds, e.g. diketo-pyrrolo-pyrrol reds. Engeltone 1115 pigment is stable to 575[degrees] F in ABS and reportedly also performs well in many other plastics, such as PE, PP, and PS.
The company has announced that it has brought six organic and inorganic pigments into hill compliance with current U.S. regulations for color plastics used in food packaging. The pigments - Engeltone Orange 2920 and Scarlet 1112 organic pigments, and Meteor Yellow Buff 7370 and Meteor Plus Bright Gold 9350, Bright Green 9440 and Teal Blue 9530 complex inorganic pigments - can be used with many resin families, including polypropylene, polyethylene, and general-purpose polystyrene.

The Liquid Coatings and Dispersions Division of Ferro Corp. has recently introduced three new products. Series 99 is a line of high strength, transparent and opaque liquid colorants for PET stretch blow molding. The concentrated colorants are composed of up to 80 wt% pigment and a liquid vehicle compatible with all PET resin formulations. Ferro says that proprietary processing techniques reduce pigment agglomerates to individual particles, which are wet-out in suspension, preventing reagglomeration and increasing the tinctorial strength and uniformity of the original pigment by 50% to 80%. The new colorants are said to promote rapid and complete distribution of color into PET resins, allowing uniform coloration of opaque and transparent bottles, even in thin wall sections, at letdowns of 100:1 to 1000:1. The colorants have received FDA approval and are available as multifunctional packages containing UV screeners to protect bottle contents.
A new black liquid colorant for injection molding, #91-88380, is reported to exhibit greater hiding power, jetness, and stability than previous formulations. This colorant incorporates "very jet" carbon black pigment into Ferro's universal liquid vehicle at 35% loadings using proprietary processing techniques. As is the case with the Series 99 colorants, pigment agglomerates are broken down into individual particles and wet-out in suspension, preventing reagglomeration and increasing opacity by 50% to 80%. The process is also said to improve anti-settling characteristics and minimize viscosity. At 5000 centipoise, the new black is pourable and pumpable, and disperses readily for uniform color distribution at recommended letdowns of 100:1 to 1000:1. The colorant is reportedly compatible with HIPS, MIPS, ABS, PVC, styrenics, polyolefins, and other thermoplastics.
According to Ferro, its new Super Black #34-81107 paste colorant for flexible urethane foam, which is made of 35 wt% to 40 wt% solids (vs. 10 wt% to 12 wt % for conventional carbon black colorants) and a totally reactive polyether polyol resin vehicle, is four to six times stronger than traditional carbon black colorants at equivalent viscosities. Again, proprietary processing reduces pigment agglomerates to individual particles, which are smaller and distribute more uniformly over urethane foam cells than do pigments of conventional carbon black colorants. The resulting increase in tinctorial strength, coupled with 190% to 300% higher pigment loadings, can reduce typical letdowns of 3.0 pph using conventional blacks to 0.5 pph using the Super Black colorant at equivalent levels of jetness.
Ferro Pigments has introduced several new products over the past year. V-10118 Pigment Brown 24 is said to show improved tinting strength. Especially recommended for use in rigid PVC siding and window profiles, the product demonstrates excellent weatherability.

Two new nonhalogen flame retardants for engineering plastics and their blends will be introduced in 1999. According to FMC, they offer a range of cost and performance advantages including excellent juicing characteristics. PC/ABS and modified PPO resins formulated with FMC nonhalogen flame retardants achieve a UL94 V-0 rating down to 0.0625 inch or thinner while maintaining good thermal and mechanical properties.
Another new area of development for FMC has been products for wire and cable that are free of heavy metals. The following two products were introduced in Europe in 1998 and will be offered to the U.S. market in 1999: Reofos 95 is a phosphate ester that reportedly gives the optimum balance of low volatility with good flame resistance. The combination of this product with flame retardant fillers is said to allow more environmentally acceptable cables to be manufactured at a cost equivalent to earlier products. The low volatility of Reofos 95 makes this product a good choice for PVC and PUR formulations that need to meet both the flammability requirements and also the high resistance to fogging specified by the automotive industry.
Reofos 35 is an isopropylated phosphate ester reported to be particularly suited to use in PVC-coated fabrics because of its combination of low viscosity, excellent flame resistance, and the ability to impart a dry finish to the coated fabric. FMC Chemical R&D Center, Process Additives Division, Princeton, NJ 08540; (609) 9513324; fax (609) 951-3382.
Henkel has announced a new line of calcium zinc stabilizers in the form of dustfree powders or granulates. Stabiol CZ 2222 reportedly provides good early color, long-term thermal stability, and good transparency in the production of flexible PVC blown film, refrigerator gaskets, and other food grade extrusions. Three products - Stabiol CZ 2868, Stabiol CZ 2938, and Stabiol CZ 2959 - are recommended for use in wire and cable applications, where long-term thermal stability, electrical properties, and high-speed processing are required. In addition, Stabiol CZ 2868 and Stabiol CZ 2959 offer low water absorption properties.
In addition to the stabilizers, Henkel has also introduced Loxiol 2986 and Loxiol 2987 as part of a new-generation paraffin-free lubricant system for rigid PVC building products. These co-stabilizing ester lubricants are said to provide improved thermal stability along with a wider processing window than conventional paraffin systems. Preliminary field trials indicate significant reductions in plateout using this type of system.

Indspec has established commercial-scale production of hydroxyethyl ether of resorcinol (HER) and has the capability of manufacturing this product at two facilities. This aromatic meta-positioned diol finds application in polyurethanes as a curative of isocyanate prepolymers. Assessment of its applicability in coatings, adhesives, sealants, and powder coatings is under way.
HER, a 1,3 isomer similar to HQEE, has been found to be much more user friendly than its 1,4 cousin. The lower melting point of HER, its tendency to supercool, and its higher degree of solubility in prepolymer mixes are reportedly providing processing and quality improvements in the cast elastomer shops while maintaining the excellent physical properties expected of an aromatic chain extender. As a barrier enhancer when synthesized into the PET backbone, HER offers improvement that appears to be related to its 1,3 linkages, as has been the case with other resorcinol derivatives.
The company's new product development has expanded beyond the introduction of HER, which is crystalline at room temperature, to aromatic diol extenders that are liquid at room temperature. These products are expected to be used in specialty urethane formulations. Indspec Chemical Corp., 411 Seventh Ave., Suite 300, Pittsburgh, PA 15219; (412) 388-2848; fax (412) 765-0439.
The Engineered Materials Division of J.M.

Lansco Colors (Landers Segal Color Co.), a distributor of pigments, has added to its line several new products that can be used by the plastics industry. Two new organic pigments are Lansco 1370 Napthol Red 170, a product reported to equal competitive types at substantial cost savings, and Lansco 5151 Phthalo Blue 15:1. a red-shade blue for polyethylene and vinyls. In addition, Lansco has announced that it is sourcing a high-quality line of conventional and encapsulated lead chromates from Japan. Another new product is Lansco 8042, a low-cost off-shore rutile titanium dioxide that is said to offer less brightness and whiteness but excellent cost savings for use in tans, buffs, and pastel shades. The company has also introduced a flame retardant, natural magnesium hydroxide, that reportedly provides major cost savings compared with the synthetic form and significant performance advantages compared with aluminum trihydrate.
Lansco Colors has also announced its move to new and larger facilities located in Montvale, N.J., effective April 20, 1998. The Smithchem Division of Lansco will also be a part of Montvale operation. Lansco Colors, 305 West Grand Ave., Montvale, NJ 07645; (973) 307-5995; fax (973) 307-5855.
Laurel Industries, an operating trait of Occidental Chemical Corp., has acquired the flame retardant business of Elf Atochem North America, Inc. The Elf Atochem flame retardant business includes Thermo-guard antimony oxide, sodium antimonate, and Pyronil brominated plasticizer additives and concentrates.
Laurel Industries reports that one of the benefits of using its flame retardant Dechlorane Plus to flame retard nylon is the ability to use different synergists and mixed synergists to give different electrical properties and also to lower the cost of the formulations. When a mixture of Dechlorane Plus and the synergists zinc borate and melamine cyanurate is used, it is possible, the company says, to achieve a CTI (comparative tracking index) of 425 volts in 25% glass-filled nylon 66. This is reported to be 200 volts greater than that of the brominated flame retardants with antimony oxide synergists. According to Laurel Industries, the new formulations have physical, mechanical, and flammability properties similar to those of conventional flame retardant glass-filled nylon formulations.
The company has also introduced an aqueous dispersion of Dechlorane Plus with antimony oxide. Known as Dechlorane Plus AD, this dispersion is 67% active and contains Dechlorane Plus/antimony oxide in a ratio of 3:1. It can be used to flame retard textiles for such applications as curtain backings. Two reported benefits of Dechlorane Plus in these applications are its excellent UV stability and its low smoke formation.

Cimpact 710C and Cimpact 710HS are new high-brightness hydrous magnesium silicates (talc). Like all of Luzenac's talcs, 710C and 710HS exhibit a platy structure. According to the manufacturer, this structure, in combination with an extremely fine particle size, provides the compounder with superior flexural modulus and impact properties. Both products are air micronized to a 7-Hegman (12.5-micron) topsize and a mean particle diameter of 1.8 microns. The compaction technology used by Luzenac reportedly provides both products with high bulk density and friability, resulting in higher extruder throughput and improved dispersion in compounds. Cimpact 710HS is a surface-modified version of Cimpact 710C. The surface treatment provides extended heat stability, higher flexural modulus, and an improved whiteness value.

The Hanna FX colorant line from M.A. Hanna Color has been expanded to include Hanna FX Metal, Hanna FX Camouflage, and Hanna FX Nite Brite. Hanna FX Metal is said to achieve the look of brushed aluminum, bronze, copper, gold, and antique brass. Additional custom formulations are also available. Compatible with a range of thermoplastic materials, the colorants have been used to produce blow molded bottles. Also available for packaging applications, Hanna FX Camouflage reportedly boosts product visibility. Use of this colorant removes the need for painting, thus eliminating a secondary finishing operation. Currently, Hanna FX Camouflage is available only for products produced by injection molding.
Another new product is the super phosphorescent Hanna FX Nite Brite. The combination of this pigment with a proprietary formulation and laser energy allows the marking of plastic electronics and telecommunications housings and also the illumination of parts that previously had been difficult to wire. According to Hanna, earlier phosphorescent colorants required high additive loadings, which made it difficult for the plastic to maintain its physical performance properties. To achieve the necessary glowing effect, traditional colorants require only a few minutes of direct exposure to light but are capable of providing only 20 to 30 min of phosphorescent light. FX Nite Brite, on the other hand, requires 30 min of ambient light exposure and achieves 10 hr of high-quality illumination. With the addition of a custom colorant into the base resin formulation of a plastic component, the finished molded part can then be marked with the M.A. Hanna Color's FastMark system.
The FastMark system develops color markings through the interaction between laser energy and custom colorants within the thermoplastic substrate. It produces marks that are very distinct while avoiding degradation of the plastic's surface. Final color is determined by both duration of exposure and the energy level of the laser. The process can also be used to mark opaque or transparent thermoplastic substrates - and work is under way to optimize packages for common thermoset polymers. Also, the system can create several shades from one background colorant. First commercially used in animal tags, the system can provide fast, in-line color marking for numerous automotive button-activated controls and PP-based interior trim components.
Wilson Color, a business unit of M.A. Hanna Co., has introduced Dry Silane Masterbatch for cable extrusion applications. Became the active crosslinking agent is in a dry, solid form, the new product eliminates the need for liquid injection and can be used in all standard extruders. A high setup temperature gives the masterbatch higher thermal stability during the grafting and extrusion process, which is said to greatly reduce the risk of plateout on the extruder screw and therefore give greater grafting efficiency. Formulated to maintain the required level of antioxidants and metal stabilizers in the final compound, Dry Silane Masterbatch reportedly forms a completely homogeneous mix with the resin to be extruded. Special stabilizers prevent premature polymerization of the system. According to the manufacturer, a uniform crosslinking ratio gives excellent aging, electrical, and mechanical properties.
M.A. Hanna has announced that its Technical Center in Suwanee, Ga., has achieved ISO 9001 certification and that now all M.A. Hanna Color operations meet ISO 9000 standards.
The company has also announced the construction of a plastics color and additives plant in Hungary, its first manufacturing presence in Eastern Europe. Harwick Chemical Manufacturing Corp., a business unit of M.A. Hanna Co., has begun construction of a 100,000-[ft.sup.2] production facility in Massilion, Ohio. The new facility will house Harwick Chemical Manufacturing's batch production of color concentrates used by the rubber and plastics industries, water-based dispersions for latex products, and chemical additive dispersions used in the rubber polymer markets. Production is expected to begin in January 1999. In addition to manufacturing, the new facility will include a 5000[ft.sup.2] office area, a product technology laboratory, and a quality assurance laboratory. Headquarters for Harwick Chemical Manufacturing will remain in Cuyahoga Falls, Ohio. Harwick Chemical is also expanding a production facility in Wynne, Ark., adding 30,000 [ft.sup.2] of space to an existing 120,000-[ft.sup.2] building.

The Plastics Additives business group of Morton International has introduced a new line of PVC heat stabilizers known as Advaflex. The totally organic molecule, Advaflex LM-300, forms the core of this new technology Used in combination with very low levels of zinc-containing compounds (and in some cases, only catalytic levels are needed), Advaflex LM-300 systems are reported to be completely free of toxic metals, hydrolytically unstable phosphites, solvents, phenolies, and VOCs. According to the manufacturer, Advaflex LM-300 systems have demonstrated performance that is equal and in many cases superior, to mixed-metal stabilizers based on barium/cadmium, barium/zinc, and cadmium/zinc technologies. Advaflex LM-300 can also be combined with traditional mixed-metal stabilizers, resulting in very high performance and leading to significantly reduced dosages of these mixed-metal products.
In addition to heat stability performance, Advaflex LM-300 systems offer the following secondary performance benefits; transparency; static heat stability; rapid air release properties in plastisols over a wide range of stabilizer dosages; low tendency to plate out, which demonstrates the very high compatibility not only with PVC and plasticizers but also with the other micro ingredients; electrical properties equivalent to those of traditional barium/zinc/phosphite when mixed in a filled cable jacketing formulation; and accelerated weathering performance similar to traditional flexible stabilizers in a filled, Ti[O.sub.2]-pigmented formulation.
The Advaflex LM-2000 series of stabilizers has been formulated using the Advaflex LM-300 molecule. Products in this series are individually designed according to the thermal requirements of each application. Specific applications are clear calender and extrusion (Advaflex LM2000), low-filled 'calender and extrusion (Advaflex LM-2005), moderately filled calender and extrusion (Advaflex LM-2010), highly filled calender and extrusion (Advaflex LM-2020), and filled plastisol (Advaflex LM-2040).

The company has introduced new PlastiStab heat stabilizers for PVC. Made at OMG's recently expanded facility in Franklin, Pa., the product line offers the benefits of carboxylate technology, which reportedly include lower odor and volatility of the heat stabilizer, and improved printability, weatherability, clarity, and resistance to autofogging in the finished film. PlastiStab 2327, 2342, 2355, and 2360, which have been developed for high-speed processes, differ in their metal content for different rates of reaction with the vinyl. Carboxylate technology, as is found in PlastiStab 2306, 2319, and 2343, also reportedly enhances plastisol processing with consistent color hold and viscosity development. For high-temperature processing in flexible, semirigid, or rigid applications where odor, clarity, and weathering requirements prevent the use of tin mercaptides, OMG provides various tin carboxylates, such as PlastiStab 2208 and 1114. The manufacturer says that food grade applications also benefit from liquid carboxylate technology. Such products as PlastiStab 2206 and 2210 are said to provide stability and rheology characteristics comparable with those of powder and paste stabilizers but with improved clarity and ease of handling.

Owens Coming has developed a reinforcement, known as Aquablok, for fiber-optic cables. Reportedly, cables containing these reinforcements, which are treated with a water-swellable coating, require fewer components, since the reinforcements provide both tensile strength and waterblocking properties. This makes the design and manufacturing process more efficient and reduces time and costs of field installation and repairs. The water-swellable tensile glass fiber strand is said to enable field personnel to rapidly perform cable termination and mid-span access. According to Owens Coming, in the past, cable manufacturers were required to use both a tensile strength component and waterproof tapes, greases, and gels. This added layers and weight to the cable, 'increasing the outer diameter and reducing the available space for optical fibers. The design also required more complex manufacturing processes, which increased the cable costs. In addition, the numerous components made it difficult to install and repair the cable.
Another new product is the Cratec Plus chopped strand system. According to the manufacturer, these pelletized glass fibers, which are 25% more compact per bundle than existing chopped strands, can help increase product flow up to 50%, improve operating environments by reducing fuzz and fines up to 80%, and reduce warehouse space required to store the product.
A further development of this system is PBT 1A1 HR. Owens Corning says that these chopped strands offer 30% better hydrolysis resistance, up to 25% better instrumental impact, and improved heat aging than other chopped strand glass fibers. PBT 1A1 HR chopped strands also offer enhanced reinforcement in higher performance flame-retardant applications. And because these chopped strands are from the Cratec Plus system, they also offer the same increased product flow, reduced fuzz and fines, and reduced storage space requirements. As indicated by the product's name, PBT 1A1 HR chopped strands are designed for use with thermoplastic polyester (PBT). Currently, the two target markets for the chopped strands are transportation and electrical. The initial applications in the automotive industry have been in areas where strength and temperature resistance are essential, including distributor caps, fuel pumps, and safety system components, such as airbags. In the electrical market, applications include connectors, automated equipment, and electrical generating/power distribution equipment.
Owens Coming also reports that recent test results from its Science and Technology Center in Granville, Ohio, show that glass fiber-reinforced polymer (GFRP) composites exposed to both alkaline and acid environments can sustain significant stress and perform for extended life cycles under harsh field conditions. During a 90-day test period, GFRP composites exposed to hydrochloric and sulfuric acid baths at 60 [degrees] C and 23 [degrees] C retained an average of 92% of their pretest tensile strength. GFRP composites containing Owens Coming Advantex glass fiber reportedly performed particularly well, retaining on average 96% of their original tensile strength. According to Owens Corning, these data will have a significant impact in civil engineering applications where steel has traditionally been the dominant reinforcing material. The deterioration of mild steel reinforcements from corrosion has been a major concern when concrete members are exposed to aggressive environments.
These recent test results are said to further support the increased use of Marshall Industries Composites' C-BAR reinforcing bar (rebar), which was developed through a partnership between that company and Owens Coming, and is said to be stronger, lighter, and more corrosion-resistant than steel rebar. The C-BAR core is composed of unidirectional Owens Coming E-glass fibers embedded in recycled PET resin material. The outer skin is a Reichhold urethane-modified vinyl ester with excellent resistance to moisture and chemicals.
Advantex EB8 texturized glass fiber yarn is another new product. Manufactured from Advantex glass fiber, EB8 yam is sized with chemicals that cannot be removed by conventional glass finishing techniques. It combines the traditional mechanical properties of E-glass with improved corrosion performance and optimum heat resistance because of a higher melting point (916 [degrees] C). This product will replace its predecessor, EB6 yarn. Advantex EB8 yarn reportedly offers enhanced weaving processability and productivity levels, improved aesthetics, high dimensional stability, noncombustibility and fire resistance, as well as stronger reinforcement. Possible applications include wall coverings, thermal insulation, and decorative and industrial fabrics.
Another new product manufactured from Advantex glass fiber, ZTY yarn, is also said to combine the excellent mechanical properties of traditional E-glass with improved corrosion performance and heat resistance. In addition, its smoother surface enhances the visual appearance of laminates and other applications. ZTY yam consists of continuous and parallel glass strands bonded by sizing to increase tensile strength and meet specific application requirements. Unlike traditional glass fiber yams, the strands are wound into a square-edged package and are not twisted, resulting in a flatter and thinner product. In addition, the yarn's sizing protects the glass filaments from abrasion during processing. Starch oil sizing can be removed or coated with a resin-compatible finish after processing. ZTY is designed for a variety of construction and industrial applications, including facade cladding, wallboard tape, roofing yam, concrete boards, and thermal insulation.
Owens Corning has also announced the formation of a joint venture that will acquire the company's yams and specialty materials business. The joint venture partner is Groupe Porcher Industries, Badinieres, France. The closing of the transaction occurred on September 30, 1998. Further business developments include a plan to add 1500 metric tons of capacity to the company's glass fiber continuous filament mat (CFM) lines in Huntingdon, Pa. This expansion, scheduled for completion in the fourth quarter of this year, follows a similar increase of 1000 metric tons in the CFM line at the company's facility in Battice, Belgium, earlier in 1998. In anticipation of continued growth, detailed engineering plans are being made for an additional CFM line to be operational in 2000. As of press time, the location for this line had not been announced. Owens Coming, One Owens Corning Pkwy, Toledo, OH 43659; (419) 2486190; website: owenscoming.com

Radiant Color reports that its Microsphere Fluorescent Pigment (MP), a highly crosslinked, spherical microparticle, does not soften upon incorporation into plastics and eliminates "hang up"in the extruder or molding machine. Thus, MP virtually eliminates staining of equipment during processing and substantially cuts cleanup time and equipment turnaround time during color changeover Reduced equipment plateout with MP means a lower incidence of surface imperfections in the molded parts. MP's combination of inertness and minimal surface area of the spherical particles are said to allow for high pigment loadings without negatively affecting resin properties. This eliminates the "puffy" strands often associated with fluorescent concentrates. The particles also allow for stable dispersions that do not build viscosity over time. According to the manufacturer, MP's nonmigrating and bleed-resistant properties make it an excellent colorant for both plasticized PVC and vinyl plastisol screen inks. It is also reported to be suitable for all major resins, including low and high-density polyethylene, polypropylene, general-purpose and high-impact polystyrene, and it can be used in all major plastics processing applications. The pigments show consistent color development from one run to the next, and the increased opacity of the highly crosslinked MP particles yields great color strength and hiding power for a given pigment concentration, especially in mass tones. MP is available as a free flowing powder in a spectrum of 11 colors.
Radiant K2000 is a series of fluorescent plastic colorants designed primarily to prepare high-load concentrates, in addition to dry and liquid colors. Allowing loadings greater than 40% without sacrificing equipment performance or slowing down processing speeds, these colorants reportedly exhibit excellent heat stability with minimal color shift at longer dwell times and at temperatures up to 550 [degrees] F. According to the manufacturer, lightfastness is equal or superior to other currently available fluorescent colorants. Dispersing rapidly with strong color development and excellent tinting strength in all major resins, K2000 colorants are said to meet performance requirements in extrusion, injection molding, rotational molding, and blow molding. Available in coarse and fine grind versions, the series is offered in 11 colors. Radiant Color, 2800 Radiant Ave., P.O.

Teknor Color has added 18 products to its line of standard dry colors for rotational molding and has increased the efficiency of these colors to enable molders to reduce use levels. According to the manufacturer, this is an important development because high color loadings can have a deleterious effect on key physical properties, particularly impact strength. Typical use levels are in the 0.125% to 0.25% range. Among the new colors are a number of greens, grays, and beiges, in addition to two heavy-metal-free "safety" colors - yellow and orange - for use in traffic pylons, road barriers, and related outdoor products.
The company has also developed color concentrates for use with Teknor Apex`s FireGuard LSNH flame retardant compounds in fiber -optic riser cables. According to Teknor Color, nonhalogenated flame retardant compounds are typically more difficult to color than halogenated ones. But the new concentrates are so efficient that they can impart intense coloration without requiring the high addition levels needed with conventional concentrates. Supplied as pellets, the concentrates are available in ten standard colors and custom-match formulations.
The company's newest product is TEKlite Color Spheres. These color concentrate microspheres have a 1/32-inch diameter, which reportedly allows them to melt and mix much more quickly than conventional 1/8-inch beads or pellets, even under processing conditions where beads have presented color-dispersion problems. Because of their minuteness and high surface-to-volume ratio, the microspheres become incorporated with the resin almost instantly, while beads require several seconds. According to Teknor, conventional concentrates are typically used at resin-to-concentrate ratios of 25:1, whereas Color Spheres can sometimes be used at 300:1 letdowns. High pigment loadings - 75% in the case of most Color Spheres - contribute to their coloring efficiency The excellent dispersibility of Teknor's new concentrates are also said to help processors avoid color variations that sometime occur in parts with long, flat surfaces. In addition, Color Spheres can be used to improve dispersion in old or worn molding presses or extruders. The colors-white, black, red, blue, green, and yellow-are supplied in two series for use in polyolefins and styrenics, respectively Formulations with U.S. FDA-sanctioned ingredients are available.
A kit has also been developed to help customers make more informed decisions about the match between Teknor Color concentrates and their own color standards. Called Your Custom Color Match, the kit is a pocket folder containing individual match chip holders produced in Munseil gray with cutouts to view the samples; three fixed viewing ports, also printed in the same neutral gray; a portable color viewing port; and standardized data sheets.
Two new brochures are also available from Teknor Color One, entitled Instex, explains how the use of Instex cryogenically ground PVC color concentrates in place Of conventional raw pigments enables dryblend compounders to improve color dispersion, enhance product quality, and reduce dusting during handling and blending. The other brochure, Color Crystals, explains how plastics processors can use Color Crystal concentrates to reduce coloring and inventory costs, save time and space, and meet special end-use requirements.

In October 1997, Ticona introduced Ceramer polyphenylene sulfone PPS[O.sub.2], a new additive that reportedly improves the wear properties and creep resistance of fluoropolymers with little or no effect on chemical stability. The additive is a very fine powder with particle size averaging about 20 [[micro]meter]. Maximum particle size is less than 70 [[micro]meter]. The particles are almost spherical with a rough cracked surface that facilitates a good mechanical bond with PTFE and other polymers. As a wear enhancer, it is suitable for use in bearings and seals where high-temperature resistance and strength are required. In protective tubing for common push-pull gear cables, the addition of Ceramer to PTFE paste extrusion powders is said to increase life significantly. According to the manufacturer, Ceramer greatly improves the metallizability of PTFE and other plastics, expanding their use in circuit boards and other electronic applications. A 10% blend of Ceramer reportedly improves by a factor of six the adhesion of copper to fluoropolymers. Electrical properties of the base resin show only negligible change.

Uniroyal reports that although Celogen 754A began its product life cycle as a chemical foaming agent developed for use in rubber, it is entering a new phase of growth in the plastic industry. A preactivated azodicarbonamide, the product features a gas release temperature of 338 [degrees] F that is said to be ideal for many flexible PVC formulations, especially molded shoe soling. In addition, processors of TPOs, TPEs, and TPUs have found this product to be an excellent choice for both molded and extruded foam applications. The Celogen 754-A activation system offers a gas release rate and behavior said to be more compatible with many polymers processed in the 338 [degrees] F to 401 [degrees] F range than those offered by standard ZnO-based or zinc stearate-based activation systems. Typical use levels for this powder vary from 0.2 to 1.0 wt% in molding and extrusion. As with most azo-based chemical foaming agents, Celogen 754-A is also an efficient source of gas, generating up to 180 to 200 cc per gram of product. Uniroyal Chemical Co.

Chopped Strand Mat M12A is a high-performance reinforcement for polyester, vinylester, bisphenol A, and isopolyester resin systems. Made from cut fibers laid in a random pattern and bonded with a powdered, highly soluble resin binder, this fine strand reinforcement has been designed for hand lay-up contact molding and other low-pressure processes. M12A is said to provide excellent fiber distribution and mat weight uniformity and exceptional dry handling and tensile properties. The fine strand input of M12A means low fiber prominence at the surface of the finished laminates. Applications include corrosion-resistant hoods and scrubber units, chemical storage tanks, large diameter pipes, boat hulls and decks, swimming pools, appliance housings, shrouds, and trays.
Chopped Strand Mat M17A is a new product designed for the same resin systems and end-uses as M12A. Many similar properties are reported - excellent fiber distribution, mat weight uniformity, and dry handling and tensile characteristics. In addition, the greater porosity of the standard strand in M17A permits rapid wet-through and wet-out with minimum air entrapment, thus enabling easy rollout.
