Carbon black –ethylene-octene copolymer (EOC-CB) composite electro-thermal properties were investigated for using the composite as self-regulating heating material.The materials electrical resistance change with temperature changewas investigated.Additionally,while a voltage of 30 V was applied, the sample temperature and electrical current strength was measured.The samples with 15 to 20 phr CB showedpositive temperature coefficient of resistivity and couldbe used as self-regulating heating materials. For different concentrations of CB the achieved equilibrium temperatures were between 30°Cto 60°C (with 30 V) and couldbe used tocomfortably warm the human body.
