A polymer resin composition having a constant temperature coefficient property with improved long-term output stability and a polymeric heating element

摘要

The present invention relates to a polymer resin composition which improves adhesion between a conductor (2) inserted in a heating element (1) and a heating element resin composition (3) to apply power when used as a polymeric heating element and thereby improves the output stability of the heating element, Wherein the resin composition of the present invention comprises a polyolefin resin having a total of 0.1 to 10 parts by weight of maleic anhydride grafted with 8 to 50 parts by weight of carbon black, 5 to 40 parts by weight of an inorganic filler, 0.1 to 10 parts by weight of phenol Based or amine-based antioxidants.
