PROBLEM TO BE SOLVED: To provide a composition for providing a rubber material which has excellent flex resistance in use in a high temperature condition, while maintaining physical properties in normal state such as tensile strength expected as the rubber material and heat resistance, and to provide a crosslinked product formed by crosslinking the composition. ! SOLUTION: It is found that an epichlorohydrin rubber material formed by crosslinking an epichlorohydrin polymer composition, which contains an epichlorohydrin polymer and surface-treated silica, has excellent flex resistance in use in a high temperature condition, while maintaining tensile strength expected as the rubber material and heat resistance. !
