CONDUCTIVE FOAM AND METHOD FOR PRODUCING CONDUCTIVE FOAM

摘要

PROBLEM TO BE SOLVED: To provide a conductive foam having conductivity which is uniform and whose change caused by temperature and humidity is remarkably improved, at a non-high cost.

SOLUTION: This conductive foam is characterized by mixing and foaming an epichlorohydrin-based rubber, a rubber capable of being co-cross-linked with the epichlorohydrin-based rubber, a foaming agent and an ionic compound. The conductive foam is characterized by foaming the raw materials to have properties comprising hardness of 15 to 50, a volume resistivity value of 1×104to 1×1010Ωcm and environmental dependency (expression log R1 – log Rh) of -1.0 to 2.0. The method for producing the conductive foam is characterized by kneading the epichlorohydrin-based rubber with the ionic compound, kneading the obtained mixture with the compounding agents and then foaming the kneaded product.
