Abstract

Thermoplastic molding compositions comprise PA1 A) from 5 to 99% by weight of a thermoplastic polymer selected from the group consisting of polyamides, polyesters, polyphenylene ethers and mixtures of these, PA1 B) from 1 to 60% by weight of red phosphorus which has been pretreated with from 0.01 to 2% by weight, based on 100% by weight of B), of a phlegmatizer and from 2 to 15% by weight of a mineral filler, PA1 C) from 0 to 70% by weight of other additives and processing aids, where the sum of the percentages by weight of components A) to C) is 100%.
