Abstract

Conductive molding materials contain PA0 (A) from 29 to 76% by weight of one or more linear thermoplastic nylons, PA0 (B) from 20 to 50% by weight of finely divided calcined kaolin and/or finely divided calcium metasilicate, which are coated with organosilanes as coupling agents, PA0 (C) from 4 to 6% by weight of conductive carbon black having a BET specific surface area >900 m.sup.2 /g and a DBP absorption >300 ml/100 g and, if required, PA0 (D) from 0 to 15% by weight of conventional additives in effective amounts, the percentages of A to D summing to 100.
