Additives annual 2006: new additives and masterbatches add versatility, value to plastics.

Developments in additives and masterbatches keep expanding the versatility of plastics, providing aesthetic improvements and advances in processing and performance. Antimicrobial additives promote good health. Lower-priced carbon nanotubes present opportunities for stronger, lighter, and electrically conductive plastics. A host of new surface-property modifiers enhance the perceived quality of plastics.

The U.S. market for plastics additives is expected to grow 4.6% each year through 2009, according to a 2005 study by the Freedonia Group that analyzes the $5.5 billion U.S. additives industry. Gains are expected to be driven by higher demand for plastics, improving markets, and the rebounding demand for plasticizers and flame retardants. The fastest growth will be in seen polypropylene formulations for packaging, automotive, and electrical and electronics, the study says. Robust gains are expected in the use of light stabilizers, antistatic agents, antioxidants, and flame retardants.

This article covers recent developments in the major additive categories, with products grouped alphabetically by functional type and manufacturer.

TEK Deck Pro can be custom-tailored to meet specific customer requirements. The biocide is added to improve aesthetics by controlling fungal growth, which can cause staining. Vinyzene biocides, containing no heavy metals, have been shown to exhibit excellent performance in accelerated weathering and field trials.

Fillers, Reinforcements, & Impact Modifiers

Bayer MaterialScience has announced the commercial launch of its Baytubes[R] brand carbon nanotubes, having succeeded in producing high-quality carbon nanotubes on an industrial scale at relatively low cost. The multiwall tubes comprise up to 15 graphite layers and have a maximum mean diameter of 50 nanometers--more than 10,000 times thinner than a human hair.

Adding small quantities of Baytubes can make a plastic car fender electrically conductive so it can be painted without pretreatment. Films for antistatic packaging materials and EMI shielding of electronic components are among other target applications.

The first product in a new line of densified chopped-strand glass fibers was introduced recently by Johns Manville. ThermoFlow[R] 600, specially designed for PBT compounds, is said to exhibit outstanding color and mechanical performance plus superior heat-aging characteristics. The product provides superior polyester matrix bonding, and its strand integrity exhibits best-in-class fiber flow, resulting in more effective fiber distribution, says the manufacturer. ThermoFlow 600 can be used in electrical and electronic applications such as connectors, housings, relays, switches, and motor end-caps.

Nanocyl S.A., a Belgian manufacturer of carbon nanotubes, has launched Nanocyl[R] 9000, a high-density polyethylene nanocomposite powder. The additive contains a very high loading of nanotubes predispersed in a polymer carrier, using a proprietary technology. Its primary use is as a concentrate for easier handling and superior dispersion of nanotubes in thermoplastics. Nanocyl 9000 is compatible with polyolefins and engineering thermoplastics (PC and PA66). Typical loading levels start at 2%.

Flame Retardants

Two new flame retardants for flexible polyurethane foam used as cushioning in furniture and automotive applications have been introduced by Chemtura Corp. Firemaster[R] 600 and Firemaster[R] 602 are said to be 10% more effective than Firemaster 550 and 552. The new products exhibit outstanding scorch resistance and cigarette smolder, have minimal effect on foam processing, and offer a favorable environmental profile, says Chemtura. Firemaster 602 is specifically formulated for mechanically cooled foams.

A unique translucent flame-retardant system for film has been introduced by Polymer Products Company. Endura FR-6973 is said to provide improved transparency and more vibrant colors than conventional FR products. Used at 10% to 15% let-down ratios in either LDPE or LLDPE, Endura FR-6973 passes stringent FR standards while providing over 85% light transmission, says Polymer Products. Like other brominated flame retardants, it should be used in. conjunction with acid-resistant UV stabilizers. Polymer Products also offers a combined system of flame-retardant and UV additives in Endura FR-6930 for this purpose.

A non-halogenated flame retardant for polyamide injection-molded parts and extruded films that can meet Europe's tough new environmental regulations has been introduced by Techmer PM. PNM13319 is well suited for polyamides in electrical and electronic applications. Also new is an improved halogenated FR concentrate, PNM13318, which shares many of the same properties of PNM 13319.

Dry blending 2%-3% of the product with a base resin enables the stretch ratio to be increased 20%-30% above standard levels, with no reduction in elongation at break, the company says. Productivity is increased because fewer breaks occur during weaving and strapping operations.

DuPont Performance Elastomers announces that Viton[R] FreeFlow[TM] Z200 fluoroelastomer process aids have been declared compliant with food-contact regulations in Europe for use in packaging films. This means that the additive now has food-contact approval in all major global markets. Viton FreeFlow was designed to increase film-line yield and eliminate melt fracture, leading to a film with excellent clarity, limited haze, high gloss, and robust tear and puncture resistance.

Honeywell Specialty Materials recently announced the expansion of its high-performance specialty lubricants for PVC extrusion. The Rheochem[R] family has grown from four to ten standard formulations. The lubricants enable the extrusion of PVC compounds with improved efficiency, at lower melt temperatures, and with a lower incidence of burning, discoloration, and plate-out, says Honeywell.

A Korean electronics manufacturer is using polycarbonate modified with CBT[R] resin from Cyclics Corp. to produce a 0.2-mm-thick digital memory card that previously was molded with ABS. This is the first commercial application of CBT resin used as an additive to improve the molding properties of PC, say Cyclics and PolymersNet Co. Ltd. of South Korea. Adding small amounts of CBT resin to PC has been shown to increase the melt flow by 30%-50%, under most conditions, while maintaining good mechanical properties, enabling processors to mold large and thin-walled parts of PC.

Struktol has introduced new engineered processing additives for wood-filled composites. The products are formulated blends of lubricants designed to provide improved surface quality, increased output rates, and a wider processing window, leading to overall improved processability, the company says. Struktol TPW 012 is an optimized blend of oleo chemicals and waxes for rigid PVC compounds. TPW 113 is recommended for wood-filled polyolefins in which improved filler dispersion and surface quality are required.

A viscosity modifier designed to reduce an extruder's cycle time and energy consumption by reducing backpressure has been introduced by Techmer PM. PM 13030 has been shown to improve throughput of viscous polyolefin resins such as ultra-high-molecular-weight HDPEs without affecting the physical properties of films, profile extrusions, or molded products. Target applications include food packaging, thermoformed parts, and pipe.

A new process-aid masterbatch for polypropylene films has been introduced by the Italian manufacturer VIBA SpA. Vibatan Process Aid 100 is said to increase the production of cast and blown extruded film by increasing melt flow and enabling higher extrusion speeds while using less energy. Vibatan is said to have no effect on the optical properties or printing performance of the film.

Repellents

A novel masterbatch designed to prevent rodents from damaging wire and cable insulation is available from Aversion Technologies. RodRepel[TM] produces a foul taste. It is 100% organic, nonhazardous, and is compatible with all thermosetting and thermoplastic polymers. The universal masterbatch, based on LDPE or EVA, is added at 1%-5%. Lab testing with cable insulation containing RodRepel demonstrated that cables bitten by rats produced an adverse reaction in the animals without harming them, None of the test animals bit into the cable again, the company notes.

Stabilizers

Chemtura offers the Anox[TM] line of stabilizers, which includes Anox BB, binary blends of hindered phenols and phosphite antioxidants, and Anox TB, ternary blends of primary antioxidants, secondary antioxidants, and thioesters.

The company recently announced a 30% capacity increase for its Anox NDB (no-dust blends), a family of homogeneous blends of additives incorporated into free-flowing, dust-flee, mechanically resistant physical formulations.

The Polymer Additives Division of Ferro Corp. has introduced five nonlead, mixed-metal heat stabilizers that are said to offer improved performance over currently available alternatives to lead stabilizers. Therm-Chek[R] 7208P is a calcium-zinc powder stabilizer for PVC compounds in high-temperature cable and automotive-wire applications. It provides outstanding dynamic and static thermal stability for excellent color-hold and a broad processing window, yielding compounds with processing characteristics similar to those of lead. Other new non-lead stabilizers are available to meet specific requirements in wire and cable applications.

The Niax additives can reduce or eliminate the formation and growth of large gas bubbles or voids between the foam and metal substrate of the panels. Effective void reduction affects line speed, expansion rate, reactivity, and foam thickness.

Surface Property Modifiers

An additive masterbatch for polyolefins designed to enhance printing-ink adhesion has been developed by A. Schulman. Part of the Polybatch[R] Film Concentrates family, the product is said to eliminate the need for surface treatment prior to printing. It opens new opportunities for applications in which printing has been compromised because of inadequate dyne level (surface energy), says Schulman, noting that most film producers would benefit by introducing the additive to their film structures.

An Ampacet slip additive developed for polyethylene-based packaging films promotes adhesive lamination to fills made with different polymers, including PET, with little or no change in the coefficient of friction. Ampacet 102794 is designed to resolve a problem in the production of flexible packaging in which friction increases as the adhesive and, often, the PET film slip out of the PE layers. The product minimizes interaction with the polyurethane adhesive commonly used in lamination, says Ampacet. Use of the product is said to keep fill movement predictable and problem-free through form, fill, and seal machines and other equipment.

Ampacet has also developed an improved antifog additive masterbatch for polyethylene-based packaging fills. Ampacet 102163U is said to reduce the formation of water droplets, retaining film clarity and shelf appeal of packaged products. Tests have shown the product to improve film clarity better than conventional antifog products.

Ciba Specialty Chemicals has introduced Irgaclear[R] XT 386, a high-efficiency clarifier for polypropylene. Derived from a new chemistry platform that features high thermal stability and high chemical integrity, the product improves the organoleptic properties of clarified polypropylene vs. conventional clarifier technologies, says Ciba. It also tolerates higher compounding and processing temperatures than many other clarifiers. Another recent launch by Ciba is Irgasurf[R] SR 100, an additive to increase scratch resistance of automotive polypropylene and thermoplastic olefin compounds.

A food-approved slip agent for polystyrene processing has been developed by Croda Polymer Additives. IncroMax PS is said to decrease surface friction by up to 40% and mold-release force by up to 32%. Other benefits include improved packing and de-nesting of molded parts, reduced scratch and scuff, easier processing, and less waste, says Croda. As little as 0.5% of IncroMax PS reduces the static and kinetic friction on the surface of polystyrene.

A new antistat for electronic packaging was recently launched by Daniseo USA. Grindsted[R] PGE 308, designed to provide antistat properties for a year or more, has demonstrated excellent performance in LDPE, LLDPE, and HDPE applications. It is said to exhibit good heat and processing stability and has no corrosive effects on polycarbonate. Also new from the company is Grindsted[R] PGE O 80, an antifog for PE film applications, which testing has shown to be more efficient and longer lasting than conventional PE antifog products.

DuPont Company recently introduced an ethylene copolymer, Biomax[TM] Strong 100, to modify polylactic acid (PLA) for improved toughness in packaging and industrial applications. PLA is a com-based, biodegradable polymer used primarily in food packaging as an alternative to PET. Blends of Biomax Strong 100 and PLA can be processed in the same equipment and under the same processing conditions recommended for PLA. Even small amounts of the additive provide toughness benefits, says DuPont. Melt thermal stability of PLA is also said to be improved with the new product.

DuPont-Mitsui Polychemicals Co. Ltd. has launched Entira[TM] AS antistatic additive for thermoplastic resins used in packaging. It is said to offer high-frequency weldability and high moisture permeability. It provides permanent antistatic properties with little bleeding, excellent processability, and miscibility with polyolefins.

New calcium stearate products developed by Ferro Corp. are said to provide improved surface quality and cost-effective processing benefits in surface-critical applications of rigid PVC and polyolefins. Available in powder and granular forms, the products are designed to maintain the functionality of calcium stearate as an acid scavenger and lubricant while improving surface quality in applications having a high sensitivity to surface imperfections.

Ingenia Polymers has introduced a high-clarity antiblock masterbatch for polyethylene film. Ingenia 1091 offers permanent antiblocking, maintaining low film haze and higher clarity than conventional antiblocking agents, says the company. In tests, 1091 outperformed diatomaceous earth, typically used as an antiblocking agent for blown film, in minimizing haze.

Techmer PM has developed a new film clarifier, PM13199, which is said to reduce haze by up to 50% in linear low-density polyethylene (LLDPE) film. The clarifier was designed to enable processors to use less expensive, stronger LLDPE rather than LDPE because of the improvement in clarity that it produces. Compared with LDPE, LLDPE allows film thickness to be trimmed by as much as 25% because of its added strength, says Techmer PM.

Also new from Techmer PM are a slip additive for PET film and sheets and an antifogging agent specifically for PP film and thermoformable sheet. PTM13320 slip additive is designed to improve extrusion efficiency and minimize sticking during downstream operations, while reducing scuffs and scratches. Another antislip, PM13025, is designed specifically for extruded polyethylene film bags shipped on pallets. It increases the surface friction, reducing slippage. The antifog product, PPM12927, is said to provide optimum clarity and transparency in PP film, offering an alternative to the antifogging additives developed for PE films that are commonly used with PP.

Forecasting Directions in Colors for Plastics

The global ColorWorks team of Clariant Masterbatches Division has launched a new trends-analysis and color-forecasting initiative called ColorForward[TM] 2007 to explore changes in culture and lifestyle and how they affect color choices and preferences. Important color themes in both mass-market and luxury consumer packaging include reflective light, see-through designs, and tactile experiences, according to Clariant.

Five societal trends linked to colors provide product designers and marketers with inspiration for the coming year. Updated editions of ColorForward, which incorporates a color wheel, color chips, and PowerPoint[TM] presentation, will be released annually, says Clariant. The company operates a global network of seven ColorWorks design and technology centers, helping customers bring color into the early stages of design, accelerate new products to market, and encourage more effective use of color.

The ColorWorks experts have determined that people are "seeking calm and simplicity in the midst of their fast-paced, high-pressure world." A positive effect can be achieved by pairing opposites: cool tones and warm tones of the same color, light with dark, flat with gloss, smooth with textured, or natural with artificial. People are also seeking "authenticity" and gravitate toward organic colors and color combinations that mimic nature, with dramatic variations in hue and texture.
