    摘要： A silicone rubber composition, which comprises 100 parts by weight of a vinyl group-introduced methylfluoroalkylvinyl-based silicone rubber obtained by copolymerization of a dimethylsiloxane copolymerization unit as the main component with 5-50% by mole of a methylfluoroalkylsiloxane copolymerization unit, and 0.2-8 parts by weight of an organic peroxide. When silica is used as a filler, it is desirable to use a surfactant for silica, and water at the same time. The present silicone rubber composition can give distinguished low-temperature characteristics and blister resistance, and thus can be used for seal materials directed to high-pressure hydrogen gas storage tanks, for example, to storage under 70 MPa, and particularly as suitable vulcanization-molding materials for O-rings, packings, gaskets, oil seals, valves, etc. High-pressure gases for storage are not limited only to hydrogen gas, but also to oxygen gas, nitrogen gas, helium gas, etc. likewise.
