Abstract

The present invention relates to a plastics molding composition based on polyarylene sulfide and/or on liquid-crystalline plastic, where the molding composition comprises carbon black and graphite and/or metal powder, the carbon black has a specific surface area of from 500 to 1500 m2/g, and a dibutyl phthalate value of from 100 to 700 ml/100 g, and the graphite has a specific surface area of from 1 to 35 m2/g. The molding compositions of the invention have good conductivities, and better flowabilities and mechanical properties.
