Abstract
The electrically and thermally conductive plastic contains a polymer and a filler embedded in the polymer, based on a semiconducting material having by doping a predetermined intrinsic electrical conductivity. The filler content is chosen such that the electrical conductivity of the plastic remains largely unchanged in the case of an increase in the filler fraction. This plastic is distinguished by high thermal and electrical--but nonmetallic--conductivity and can be used advantageously for embedding the carrier material of a laminate serving in electrical machine construction for supporting the stator windings of large rotating machines.
