Abstract

PURPOSE: To obtain exothermic material with stable resistance value in such a way that electroconductive particle, crystalline high molecular material are mixingly kneaded with a material to be inhomogenous nucleus to this crystalline high molecular material.
CONSTITUTION: An exothermic material obtained in such a way that electroconductive particle composed of 40 weight % of furnace system carbon black, for example crystalline high molecular material composed of 55 weight % of polyfluoro- vinylidene, and material with inhomogenous nucleus to crystal composed of 5 weight % of potassium chloride are mixingly kneaded and formed is characterized into (a) curve in rising time of temperature, into b curve in falling time of temperature, in comparison with conventional example in c curve in case where the material to be inhomogenous nucleus to the crystal is not mixed, it facilitates to obtain the characteristics of stability with less hysteresis in the resistance value owing to the temperature.
