Abstract:
A fluororubber composition comprising(A) a liquid perfluoro compound having at least two alkenyl groups in the molecule and a divalent perfluoroalkylene or perfluoropolyether structure in the backbone, (B) a compound capable of addition reaction having at least two hydrosilyl groups in the molecule, components (A) and (B) being combined in such amounts as to give a molar ratio of hydrosilyl groups in component (B) to alkenyl groups in component (A) of 0.1/1 to 0.99/1 and precured in the presence of an addition reaction catalyst to form a precured base, (C) 1 to 100 parts by weight per 100 parts by weight of component (A) of a reinforcing filler, and (D) 0.1 to 10 parts by weight per 100 parts by weight of component (A) of a peroxide crosslinking agent containing an isopropyl monocarbonate group in the molecule.
