Title: COMPOSITION FOR HEAT-RESISTANT RUBBER, AND CROSSLINKED PRODUCT THEREOF
Abstract:
Provided are a rubber material having excellent heat-aging resistance characteristics that uses an epichlorohydrin-based polymer in which excellent heat resistance and tensile strength sought in a rubber material can be anticipated, and a composition for the rubber material. The composition is a rubber composition characterized by containing (A) an epochlorohydrin-based polymer, (B) magnesium carbonate, (C) a crosslinking agent, and (D) an inorganic filler surface-treated with a silane coupling agent, and the rubber material is an epichlorohydrin-based rubber material obtained by crosslinking the rubber composition.
