New Honeywell nylon aimed at gas-assist A new nylon especially designed for gas-assisted injection molding has been developed by Honeywell Engineered Applications and Solutions.
The Morris Township, N.J., firm said Capron SEGM35 H1 gives improved surface appearance at the slower fill speeds and melt front hesitation associated with gas assist.
Honeywell said it is well-suited to applications such as vehicle mirror housings, roof racks, door handles and bezels.
The new material, containing 15 percent glass fiber and 25 percent mineral, provides fewer sink marks, less warpage and faster cycle times, Honeywell claims.

Burlington Scientific adds spicy additive
Burlington Scientific Corp. has invented a hotter-than-pepper chemical to discourage rodents from biting through and damaging fiber optic and other expensive cables coated with polymers.
The Farmingdale, N.Y., company said it has patented denatonium capsaicinate in the United States.
The chemical is bitter, pungent and hundreds of times spicier than the most potent habanero peppers, Burlington claims. It can discourage attack from rodents and other pests and also acts an environmentally friendly fungicide, insect repellent and antifoulant.
Burlington said it plans to commercially produce the chemical in mid-2000.

BFGoodrich PP alloy lowers surface static
BFGoodrich Performance Materials debuted a static-dissipative polypropylene alloy for uses such as material handling products for semiconductors and medical devices.
Stat-Rite S-250 achieves consistent surface resistance without the use of carbon black or antistatic agents.
The Cleveland-based company said the new alloy gives clean, permanent electrostatic discharge protection that is two orders of magnitude lower in surface resistance than conventional ESD control systems.
BFGoodrich claims it introduces ESD properties early in the production process, when it increases charge carriers available during polymerization of the alloy. This helps the alloy avoid ionic or particulate contaminants and means it doesn't need humidity to be effective.

Nyco boosts impact of wollastonite grades
Nyco Minerals Inc. introduced two high-impact grades of wollastonite mineral filler for polyolefins.
Nyglos 8 10972 and M 15 Wollastocoat 10042 are fine-diameter, high-aspect ratio products that can boost notched Izod impact strengths by 20-30 percent compared with conventional wollastonite, according to the Willsboro, N.Y., company.
Nyco aims the new materials at automotive exterior and interior applications, especially thin-walled fascias and instrument panels.
Nyco claims they provide improved mar and scratch resistance.
