Resistance heating element of thermoplastic materials

摘要

A resistance heating element comprises a fiber-reinforced thermoplastic material having 1-60% by weight of glass fibers and having 1-20, preferably 5-15% by weight of steel fibers. The heating element can be prepared from thermoplastic granules which are filled with glass fibers and steel fibers and which have been obtained by melt pultrusion of continuous fiber strands and cutting to granule length.
