Abstract
A crosslinkable fluororubber composition comprising (A) a polymer comprising a perfluoro compound having at least two alkenyl groups and a divalent perfluoroalkylene or perfluoropolyether structure a compound having at least two hydrosilyl groups, the hydrosilyl-bearing compound being added to some of the alkenyl groups in the perfluoro compound, (B) a reinforcing filler, and (C) a crosslinking agent having a hydrosilyl group and capable of addition reaction or a peroxide crosslinking agent, and (D) a surface treating agent having at least one fluoroalkenyl group and silanol group in the molecule, is roll millable and compression moldable. It cures into products having satisfactory solvent resistance, chemical resistance, heat resistance, and low-temperature properties.
