Abstract
Abstract Filler-containing thermoplastic molding materials containing, as essential components, A) from 10 to 84% by weight of a thermoplastic polyamide, B) from 10 to 84% by weight of a modified polyphenylene ether, C) from 5 to 40% by weight of a fibrous or particulate filler or a mixture thereof, and D) from 1 to 20% by weight of a zinc sulfide pigment, and, in addition, E) from 0 to 30% by weight of an impact-modifying rubber and F) from 0 to 25% by weight of a flameproofing agent, are described.
