摘要:
A silicone rubber composition composed of a high-molecular diorganopolysiloxane, a reinforcing silica filler and an organic peroxide as a curing agent is further compounded with a fluorine-containing low-polymeric compound such as poly(chlorotrifluoroethylene) and perfluorinated polyether compound of the formula F--[--CF(CF.sub.3)--CF.sub.2 --O--].sub.v --O--CF.sub.2 --CF.sub.3, in which v is 2 to 100, as well as fluoroalkyl-substituted organopolysiloxanes. The silicone rubber composition can give a cured silicone rubber product having greatly improved resistance against dynamic fatigue as in repeated cycles of stretching and relaxation.
