Abstract
Abstract Filler-containing thermoplastic molding materials contain, as essential components, A) from 10 to 84.8% by weight of a thermoplastic polyamide, B) from 10 to 84.8% by weight of a modified polyphenylene ether, C) from 5 to 50% by weight of glass fibers or carbon fibers or a mixture thereof, having a median fiber length 1 50 of from 150 to 400 μm, and D) from 0.2 to 4% by weight of a pigment and in addition E) from 0 to 4% by weight of a rubber impact modifier, F) from 0 to 20% by weight of a particulate filler which differs from D) and G) from 0 to 20% by weight of a flameproofing agent.
