Abstract

Unreinforced polyamide molding materials contain PA1 A) from 60 to 100% by weight of a mixture consisting of PA2 A.sub.1) from 97.5 to 99.85% by weight of one or more polyamides, PA2 A.sub.2) from 0.05 to 0.5% by weight of aluminum hydroxide and PA2 A.sub.3) from 0.1 to 2% by weight of one or more esters or amides of saturated or unsaturated aliphatic carboxylic acids of 10 to 40 carbon atoms with aliphatic saturated alcohols or amines of 2 to 40 carbon atoms PA1 and, based on the total weight of the polyamide molding material, PA1 B) from 0 to 40% by weight of a toughened polymer and PA1 C) from 0 to 10% by weight of conventional additives in effective amounts.
