PROBLEM TO BE SOLVED: To provide an epichlorohydrin-based rubber composition having proper bending durability while maintaining tensile strength and heat resistance expected as a rubber material, and to provide a vulcanizate obtained by vulcanizing the composition.SOLUTION: There are provided: an epichlorohydrin-based rubber selected from an epichlorohydrin homopolymer, an epichlorohydrin-ethylene oxide copolymer and an epichlorohydrin-ethylene oxide-allylglycidyl ether terpolymer; an epichlorohydrin-based rubber composition containing wet-process silica and a silane coupling agent; and an epichlorohydrin-based rubber material obtained by vulcanizing the composition. |
