摘要： PURPOSE:To maintain a stable resistance constantly and to improve mechanical strength and heat resistance by mixing conductive material and non-conductive inorganic additive admixture to polymer. CONSTITUTION:A polymer PTC element is constituted by including polymer and conductive material as well as non-conductive inorganic admixture which are mixed to this polymer. For example, in the polymer PTC element including titanium acid potassium, micro crack, etc., is hard to occur due to mixture of carbon black and potassium titanate. The thermal expansion of polymer is restricted near its softening point, resistance change rate is small as compared with that which does not include a non-conductive inorganic admixture, and a stable resistance can be obtained. It allows a constantly stable resistance to be retained and mechanical strength and heat resistance to be improved.
