Higher flow, higher heat, higher barrier, higher clarity, higher stiffness, lower durometer, lower smoke, lower odor--materials exhibits at the recent K 2004 show in Dusseldorf were stretching the bounds of processing and performance properties in all directions. There was ample news in engineering thermoplastics, styrenics, polyolefins, and even thermosets thermosets, materials that can not be softened on heating. In thermosetting polymers, the polymer chains are joined (or cross-linked) by intermolecular bonding. Thermosets are usually supplied as partially polymerized or as monomer-polymer mixtures. . (Many new materials not mentioned here were covered in our September show preview.)

Wacker-Chemie of Germany (parent of Wacker Wacker may refer to:
Geniomer, like some TPU TPU - Text Processing Utility materials, forms physical crosslinks when it cools from the melt. These crosslinks are reversible when reheated, providing true thermoplasticity. Geniomer can be processed by all thermoplastic methods. Four grades are currently available (see table) with hardnesses from 40 to 60 Shore A. Price is a little higher than thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. LSRs.
Geniomer is highly transparent. It contains no catalysts, free volatile silicone components, fillers, or plasticizers. Its chemical purity is said to be suitable for medical uses, and its clarity suggest automotive applications (it is being tested as a soundproofing Soundproofing is any means of reducing the intensity of sound with respect to a specified source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to block or absorb the energy of the sound sheet for laminating on car windows). It possesses the inherent qualities of silicones--uv resistance, gas permeability, and good release and slip properties. It is paintable and can serve as a flexible bonding agent between plastics and glass or metal. It can also be used at low levels (0.1% to 0.2%) as a processing aid for other polymers to improve flow, low-temperature flexibility, and water repellence.
Another brand-new TPE is being brought to market by two companies. It is a triblock copolymer of styrene-isobutylene-styrene (SIBS). It is a 100% saturated polymer and therefore very heat--and light-stable, according to Kaneka of Japan, whose new Sibstar family is commercially available for around $2.75 to $2.95/1b. Its higher price than other SBCs suits it to niche applications. A prime example is seals, owing to the resin's excellent gas-barrier (similar to thermoset PIB See NIST binary. rubber) and mechanical-damping properties. SIBS is also inherently softer (without added oils) than other styrenic TPEs of equivalent styrene sty·rene

Terpalex is a new terpolymer of nylons 6, 66, and 12 from Ube Industries. It was developed for food packaging and is said to provide high transparency plus deep-drawability and greater shrinkability than other nylons. It has clarity and gloss comparable to nylon 612 and a slightly lower melting point than nylon 612 or 6/66 copolymer. It also boasts excellent processability in blown and cast film and good pinhole resistance. Monofilaments are another potential market.

Supradel HTS permits clear applications that formerly were limited to opaque crystalline materials like glass-filled PEEK.
Supradel HTS can be injection molded (and probably extruded) at temperatures around 275 to 280 F, though it has fairly high viscosity, like Solvay's Radel sulfones. The material is inherently flame resistant, hydrolysis hydrolysis (hīdrŏl`ĭsĭs), chemical reaction of a compound with water, usually resulting in the formation of one or more new compounds. resistant (it can withstand high-temperature steam), and is relatively tough, like Radel A polyethersulfone. Unlike thermoplastic polyimides, it reportedly requires no annealing annealing (ənēl`ĭng), process in which glass, metals, and other materials are treated to render them less brittle and more workable. and the melt is more thermally stable. At this early stage, it is yellow in color. Price is similar to that of PEEK ($33 to $40/lb).
Meanwhile, Solvay has reduced the yellow color of polysulfone to approach the clarity of polycarbonate. Its new low-color Udel P-1700 HC is nearly water white. Radel R polyphenylsulfone also now has lower color. New Radel R-5800 TR comes in a series of transparent colors suitable for color-coded medical uses. Also new is Radel R 7000, a clear grade for aircraft interiors that can be extruded into large sheets.
Other news in high-temperature resins includes high-flow PEEK grades from Victrex for thin-wall and highly filled parts. Both Victrex 90P (powder) and 90G (pellets) have an 84 MFR MFR,
n See myofascial release. , which is more than twice that of standard PEEK. They also provide a 60% improvement in spiral flow over standard products. The material is targeted for thin-wall parts such electrical connectors, where PEEK has been unsuitable due to mold-filling difficulties.
Meanwhile, ultra-high-purity Victrex 450 U002 is claimed to meet the strict requirements for extractables in dean rooms, chemical processing, and electronics. The new product, which contains less than 1 ppm of metals, is aimed at semiconductor processing components such as focus rings, fasteners, chamber insulators, and seals.
Chevron Phillips Chemicals recently introduced a new member of its Xtel PPS (Packets Per Second) The measurement of activity in a local area network (LAN).

The second generation of Durethan EasyFlow nylon 6 from Lanxess reportedly boosts flow by about 22%. It allows lower melt temperatures, which shorten cycle times. Tests show that auto intake manifolds can be molded at a melt temperature of 250 to 285 C versus 280 to 313 C for a standard nylon 6. As a result, cycle time is reduced 15%. High flow also creates more design options for production of thin-wall components with good surface quality.

PBT Paper Based Test (education) was claimed by BASF, whose new Ultradur High Speed reportedly flows at least twice as far on spiral-flow tests as standard Ultradur B4300 grades (see photo). The new "rheology-modified" version is said to cut cycle times by up to 30% without any sacrifice in properties, thanks to an organic additive that is soluble in the melt but forms separate nano-scale domains when the melt cools. BASF technicians say the viscosity curve is of the same shape as normal, just shied downward. In one test application, a sun roof was molded successfully with four of its eight hot-runner nozzles blocked off, producing fewer weld lines. In other tests, BASF was able to drop the melt temperature by 30[degrees] C and injection and holding pressures by 50%. High Speed versions of Ultradur B4300 come with 10%, 20% and 30% glass. Later, BASF plans to use Ultradur High Speed in PBT/ASA and PBT/PET blends.
In the same vein, Lanxess introduced Pocan DP 1105 Easy Flow PBT, which boasts good impact strength. Other new PBTs include Pocan hydrolysis-resistant KU2-7111 from Lanxess and its new Pocan DP2004 for electrical housings. The latter has good toughness and is halogen-free. It meets Glow Wire specs and has a CTI (Computer Telephone Integration) Combining data with voice systems in order to enhance telephone services. For example, automatic number identification (ANI) allows a caller's records to be retrieved from the database while the call is routed to the appropriate party. of 600 V.
Nylons get more muscle
Rhodia unveiled Technyl SI "super-impact" grades, a new range of modified nylon 6 with an exceptional impact/stiffness balance. These materials offer 20% more impact than other high-impact nylons together with equal or higher stiffness. A key market is power tools, where manufacturers have had to compromise between high impact and stiffness. Other markets include machine components, sporting goods, and personal-protection equipment.
Rhodia is offering three unfilled grades and two with 30% glass. They cost 10% to 15% more than typical impact-modified grades.
Rhodia also launched Technyl Force resins, a new series of long-glass nylons for injection molded auto parts. The high flow of the matrix resin reportedly results in lower shear, thereby enhancing fiber-length retention and impact strength. Technyl Force is also said to deliver processing benefits such as faster cycles, lower injection pressure and clamping force, and reduced processing temperature. Four grades have glass loadings from 30% to 60%.
Similarly, DuPont has come out with so-called "superstructural" resins aimed at metal-replacement applications and other demanding uses. These include its first long-fiber grades and others with high loadings of short fibers. Three Zytel nylon 66 grades and one Zytel HTN HTN Hypertension

Lanxess has extended the effort of Bayer (its former parent) in metal/plastic hybrid technology for auto front ends with the introduction of a new nylon 6 with 60% glass. This highly rigid Durethan grade has tensile modulus of 2.9 million psi, more than twice that of standard 30% glass-filled nylon 6. Even at 170 C, the new material has tensile modulus of 971,500 psi. Lanxess says the rigidity of the nylon allows for more plastic than metal to be used in the hybrid construction. The nylon can be formed more easily than metal in complex areas, reducing production costs. The material, which beasts strong creep resistance, is being considered for under-hood uses such as intake pipes, valve covers, and off pans.
Also new from Lanxess is Durethan DP 1803/10 H3.0, a 10% glass-filled nylon 6 for circuit breakers. It boasts good flow in thin walls, very good electrical properties, and halogen-free flame retardancy that meets European Glow Wire standards (GWIT GWIT Geneva Women in International Trade (Geneva, Switzerland) of 775 C and GWFI of 960 C).

That combination solons the nylon 12, boosting impact resistance at--40 C plus resistance to water/glycol mixtures and hot air (130 C). Upcoming developments for cooling lines are a nylon 11 for temperatures above 120 C and a multi-layer system for above 130 C.
An unusual nylon compound designed for purging engineering thermoplastics was introduced by BASF. Ultramid Ultraclean 290 is unfilled and non-abrasive. It softens but does not melt and is described as having a "sponge-like" action to scrub resins from processing machines. It can be used to speed purging of any resin at up to 280 C (536 F) and is said to perform well in narrow hot-tanner channels.

Among several new PP resins from Borealis are Borcom "microcomposites" for auto interior and appliance parts. They contain a proprietary mineral "micro-filler" of up to 10 micron size that improves properties at half the typical 20% loading of standard fillers sized at 20 to 50 microns. The result is said to be weight savings from 8% to 24%. Special compounding technology is used to obtain a fine dispersion of the microfiller. New grades include Borcom WG 140AI for auto interiors and appliances, WE 007E for "zero-gap" auto exterior trim, and another grade for high-impact auto exterior parts.
Borealis also introduced five Advanced Borseal terpolymers of ethylene-propylene-butylene designed for BOPP films. Their improved heat stability reportedly cuts down on fumes and die deposits while also improving gloss (especially when metalized) and reducing haze. The resin comes with or without slip and/or antiblock.
Also new is Borpact SG930MO, a clarified PP for frozen-food packaging that's said to combine toughness with clarity. There's also BorECO BA122E for non-pressure pipe, which boasts an improved balance of toughness and stiffness. Its flex modulus is >275,500 psi. And new PP1112 compound reportedly overcomes dimensional stability problems that have prevented PP from competing with PBT in fiber-optic cable.
New Beta-PPR RA7050 is a random copolymer said to offer a "step change" in design strength for hot- and cold-water pipe. Its design strength of 5 MPa (725 psi) at 70 C for 50 yr is more than 50% higher than the current standard of 3.21 MPa (465 psi). As a result, pipes can be made thinner than before, saving resin while allowing larger I.D. for less pressure drop.
Three new Exxtral filled PP impact copolymers for automotive are available from ExxonMobil. Exxtral BMT BMT bone marrow transplantation.

HTA Hochschule für Technik und Architektur 108 grade (0.961 g/cc, 0.7 MI) increases stiffness without sacrificing clarity or toughness (impact, tear, and puncture resistance), according to the company. Its 1% secant secant, in mathematics.
1 In geometry, a secant is a straight line cutting a curve or surface. If it intersects the curve in two different points, as in the secant of a circle, the segment of the secant between the points is called a chord. modulus is 181,250 psi MD, 246,500 psi TD. The resin is said to be relatively non-splitty, low in gels, and easy to process.
Also new from ExxonMobil is an LLDPE tailored for silane-crosslinked low-voltage power cable insulation. New LL 400EL (0.924 g/cc) reportedly has a unique combination of easy flow (3.6 MI) and rapid crosslinking with both one-step and two-step silane processes.

MDPE Maximum Permissible Dose Equivalent or PP. The new black grade combines easy process-ability for high outputs and optimum thickness control with the toughness of HDPE. On the new pipeline from Baku, Azerbaijan, to Turkey, the new grade is the outer layer in a three-layer construction that starts with epoxy primer and a Borcoat ME0420 MA-grafted PE tie layer.
Easier processing is said to characterize second-generation metallocene PEs from Total Petrochemicals (formerly Atofina). Newest additions to this series are at least seven ER grades of mMDPE and mHDPE (0.930 to 0.960 g/cc) for cast film. Applications include hygiene film and special multi-layer stretch films where no cling is required on one side. One grade, ER 2299 (0.940 g/cc, 4 MI), is said to produce very soft films with only 10% LDPE LDPE
low-density polyethylene added.
Total is also launching a new generation of mPEs for rotomolding. The first grade is M 3581 UV, available in pellet and powder. It is said to combine the superior mechanical properties of mPE with easy grinding, fast sintering sintering, process of forming objects from a metal powder by heating the powder at a temperature below its melting point. In the production of small metal objects it is often not practical to cast them. , fast densification, easy air removal, and no need for slow cooling. It also boasts outstanding gloss.
In barrier resins, Eval Europe introduced a new EVOH EVOH Ethylene Vinyl Alcohol Polymer (chemical industry) that features four to 10 times the orientation of typical grades. In thermoforming, Eval SP reportedly offers a wider processing window--close to that of PP and PS--for deep and unusual shapes. And in shrink film, it can be oriented on conventional tenter-frame or double-bubble lines. Eval SP is also claimed to offer strong delamination delamination /de·lam·i·na·tion/ (de-lam?i-na´shun) separation into layers, as of the blastoderm.

2. resistance in multilayer PET bottles. Four grades with different barrier levels are expected to penetrate new applications including shrink bags, casings, and deep-draw packaging.
Arkema introduced its first grained polyolefin to bond PP to metal foil. Orevac 18370 is aimed at laminated films to package candy and snacks. In the outer layer of cast and metalized PP film, this tie layer reportedly provides five to 10 times greater adhesion to the metalized layer.
Wacker-Chemie introduced its first fluorinated fluorinated

FLR Force of Lower Readiness is much more resistant to oils and fuels at under-hood temperatures up to 180 C (356 F). It reportedly processes like standard LSR 1. (networking) LSR - Label Switching Router.
2. (operating system) LSR - Local Shared Resources. , is fast cycling, and does not stick to molds. Initial grades of 40 and 60 Shore A are said to show good compression set and no surface tack.
Wacker also came out with a new "self-adhesive" two-part LSR with much improved mechanical properties. It is an extension of the Elastosil LR 307X family, which adheres to many thermoplastics, thermosets, elastomers, and metals (but not hardened steel molds). They can be used in overmolding without primers. New transparent and FDA-compliant Elastosil LR 3471 has 50 Shore Ahardness, tensile strength of 1336 psi, 500% ultimate elongation, and tear strength of 7733 psi.
