Conductive polymer composition for a ptc - element with reduced ntc - properties under use of carbon - nanotubes

摘要

The present invention relates to a conductive polymer composition for a ptc - element with reduced ntc - properties, the carbon - nanotubes, a ptc - binder resin and a resin based on cellulose or polyester for fixing the carbon - nanotubes and of the ptc - binder are used, and a ptc - element, a circuit and a flat or planar heating element, which have the same use.
