Ashland debuts resin suited for pultrusion
Ashland Performance Materials has introduced a new formula for Envirez unsatured polyester resin to make it suited for use in pultrusion.
Envirez 50830's high reactivity supports fast line speeds in pultrusion. It is suited to window lineals and other building components.
An extra feature is that Envirez 50380 contains recycled materials and therefore can contribute points under the U.S. Green Building Council's Leadership in Energy and Conservation Design (LEED) ratings, according to the Dublin, Ohio-based firm.

NatureWorks LLC improves Ingeo PLA
NatureWorks LLC has debuted an improved injection molding grade of its Ingeo polylactic acid biopolymer.
IngeoT 3251D improves productivity through shorter molding cycles. Molds and screws are the same as those used for styrenics. In some cases downgauging is possible and there is a potential for energy savings.
The Minnetonka, Minn., company says the new polymer is designed for semidurable consumer products such as electronics, cosmetics, housewares, toys and custom molding. It allows sustainable practice while retaining properties found in oil-based plastics.

Fortron grade meets low-halogen demand
Ticona Engineering Polymers is offering a new, low-viscosity grade of Fortron polyphenylene sulfide to meet demand for low-halogen materials.
Ticona says the new Fortron 1140LC6 is a drop-in replacement in existing molds for its recently introduced low-chlorine Fortron. The new grade contains less than 900 parts per million of bromine and chlorine and satisfies the UL94 V-0 flammability rating without the addition of flame retardants. It also withstands temperatures up to 518° F. End uses include connectors, switches and applications such as jigs for semiconductor production.

Axel's new additive reduces scratching
Axel Plastics Research Laboratories Inc. has developed a blend of modified polymers and organic fatty amides that improves the scratch and mar resistance of automotive-grade thermoplastic polyolefins.
Axel, of Woodside, N.Y., says MoldWiz Int-35cpd reduces scratching at loading levels as low as 1-2 percent. At this addition rate, no scratching was evident at 2.25 pounds of force; low-depth scratching occurred at forces up to 4.5 pounds.
Axel claims the additive's benefits include reduced resin viscosity in extrusion and as much as 3 percent less ejection force in injection molding, and that it has no effect on modulus, peak stress and thermal properties.
