GLS series of TPEs for medical industry
GLS Corp. is launching a series of thermoplastic elastomers designed for dynamic-seal gaskets and static-seal stoppers for the health-care industry.
The new specialty Versaflex TPEs are phthalate-free materials that combine the performance, design flexibility and cost benefits of TPEs with traditional thermoset elastomers. They also don't contain halogens, polynuclear aromatics, nitrosamines and other additives that can be controversial.
GLS said the new elastomers are particularly clean; have low permeation, leachables and extraction; and provide effective sealing performance to safeguard the integrity of medical fluids. They can be overmolded onto polyolefins.
GLS of McHenry, Ill., recently was acquired by PolyOne Corp. of Avon Lake, Ohio.

Carclo swaps gelatin for PVOH capsules
Carclo Technical Plastics is supplying polyvinyl alcohol capsules as a replacement for gelatin in veterinary medicines.
PVOH is water soluble and is engineered to be highly repeatable in capsule production. Such capsules are inherently nonstatic and don't deteriorate in hot and humid environments.
In addition to medicines, Carclo of Latrobe, Pa., said PVOH also can be used in medical devices and components.

Clariant increasing `green' addititives
Clariant Masterbatches has grown its lineup of environmentally friendly additive masterbatches.
The new products, branded Cesa-natur, include masterbatches for slip/anti-block agents, ultraviolet and light stabilizers, antioxidants and anti-static agents. They are blended into a biopolymer carrier resin and feature naturally occurring substances that are renewable, biodegradable and, in most cases, compostable, according to Clariant of Muttenz, Switzerland.
Cesa-natur products can be blended with biopolymers and in conventional synthetic resins. The slip-additive version performs well in polylactic acid film applications, the firm said. UV-protection masterbatches also shield package contents from light and contain naturally occurring aromatic molecules.
Also new is Cesa-extend. When added to biopolymers, the masterbatch addresses their tendency to degrade during processing.
Cesa-extend can improve melt strength of PLA for more reliable sheet extrusion and better bubble formation and stability in blown film systems. When added to PLA containing Hydrocerol chemical foaming agent, Cesa-extend enhances molecular weight and melt strength for a more easily controllable foaming process, the company said.

Ticona touting grade of long-glass fiber
Ticona Engineering Polymers boasts that its new Hostaform grade can outperform standard reinforced thermoplastics.
The Florence, Ky., firm has introduced a long-glass-fiber acetal copolymer for structural applications such as automotive parts, appliance components and gears.
It exhibits high impact resistance, inherent lubricity, and fuel and chemical resistance. It also has better temperature resistance than standard polyolefin-based long-fiber products and lower moisture absorption than standard nylons, according to Ticona. Its impact, creep and stiffness performance make it suited for structural end uses.

Carbolytic creates coloring alternative
Carbolytic Materials Co. boasts that it has created a cost-effective alternative to carbon black for plastics pigmentation.
The Maryville, Mo., company uses scrap tires to make its ApexCM carbon black replacement. The firm treats tires to recover original materials as oil, gas and the reinforcing carbon that becomes ApexCM. Carbolytic's new plant can make 10 million pounds of the replacement per year.
Automotive, construction, agriculture and industrial equipment are targeted markets for the new materials.

Polyvel concentrates for cross-linking PE
Polyvel Inc. has developed a line of pelletized peroxide concentrates for use in cross-linking polyethylene.
The PCL series is free flowing and safer to use than alkyl peroxide powders and liquids, Polyvel claims. For example, it doesn't form bridges in metering equipment as powders sometimes do, allowing for more precise dosing. As well, the concentrates maintain longer shelf life than powders and liquids, according to the Hammonton, N.J., company.
Loadings from 1-40 percent are available in a variety of carriers.
The concentrates can be let down in extrusion, injection and blow molding and rotational molding. Cross-linking leads to greater melt strength and higher mechanical values such as tensile, flexural and impact strength. Alternatively, part weight can be reduced while maintaining strength, the company suggests.

Dynamix compounds are static resistant
Polymer Dynamix introduced a family of permanently anti-static thermoplastic compounds.
DynaStat compounds are designed to give surface and volume resistivity in the critical range for sensitive electronic equipment. The materials are suitable for extrusion and injection molding and are also available in rod and sheet form for machining. DynaStat compounds are offered in a variety of resins, including nylon, acetal, ABS, polycarbonate, polypropylene and polyethylene.
The South Plainfield, N.J., firm said its new lineup relies on intrinsically dissipative polymer and Pebax thermoplastic elastomer made by Arkema Corp.
The compounds are ultraviolet stable and permanent with no migration of additives that can interfere with performance. The products maintain static control at humidity as low as 15 percent.
ExxonMobil markets its translucent TPEs
ExxonMobil Chemical Co.'s transparent and translucent thermoplastic elastomers are designed for grip applications.
The two grades are targeted at kitchenware, consumer electronics, tools and other markets.
They are dishwasher safe and can replace PVC, the company claims. The TPEs also accept special effects such as metallic, iridescent and transparent colors.
ExxonMobil TPE F471-60 is transparent with 82 percent light transmittance. TPE F371-60, the translucent grade, has a light transmittance of 10 percent.
Both grades exhibit high flow. With a hardness of 60 Shore A, they provide a soft, rubbery touch.
The Houston company says they are odor-free and have good chemical resistance. They adhere well to polypropylene in two-shot molding or overmolding techniques.
The grades complement the company's other TPEs for grip, aesthetic and comfort applications.

Masterbatches using Milliken colorants
Technologies from Clariant Masterbatches and Milliken & Co. are combined in Clariant's new masterbatches that are suitable for clarified polypropylene.
The result is sparkling colors and high reflectivity derived from Clariant's Enigma reflections special effects and Milliken's ClearTint transparent colorants. Clariant will supply the masterbatches even in small-lot sizes.
The Milliken colorants will be available in masterbatches under the Enigma brand name in a range of transparent colors and in combination with reflective special effects. These include iridescent pearls and Spectrachrome, a multicolor flip technology using complementary or contrasting color particles.
Clarified PP can be difficult to color because dyes can migrate out of the material and pigments usually reduce clarity. The companies say ClearTint colorants, however, are stable and don't diminish clarity.
Clariant Masterbatches is headquartered in Muttenz, Switzerland, with an office in Holden, Mass. Milliken is based in Spartanburg, S.C.

Bayer blend provides resistance to flames
Bayer MaterialScience LLC said its new class of polycarbonate/polyester resins doesn't rely on brominated or chlorinated additives or heavy metals.
The Pittsburgh-based firm says Makroblend EC grades now available are unfilled materials with a balance of flame resistance, toughness, chemical resistance and dimensional stability.
They provide improved fire-resistant protection and compliance with global environmental standards, according to Bayer MaterialScience. Grades are available in ultraviolet-stabilized versions.
The Makroblend EC series has received Germany's Blue Angel certification for products that are environmentally friendly. They are also compliant with the European Union's Restriction of Hazardous Substances and Waste Electrical and Electronics Equipment directives.

Nova film resin offers
good moisture barrier
Nova Chemicals Corp. has introduced a packaging film resin with a moisture barrier up to 50 percent better than competing high density polyethylenes.
Surpass HPs167-AB is designed for barrier film structures. It allows designers to downgauge films without sacrificing performance and while also improving sustainability. Alternatively, film gauge can be maintained with much high barrier and stiffness performance.
The Pittsburgh-based firm said the resin is well-suited for multilayer packaging for items such as cereal and snack liners, meats and cheeses, ready-to-eat meals, pet foods and horticultural applications.
