ABSTRACT:
The silicone rubber composition comprises, in addition to the conventional ingredients of a high-polymeric diorganopolysiloxane and a reinforcing silica filler, a specific phosphorus-containing organic compound, such as phosphinates, phosphonates and phosphates, in a limited amount. By virtue of this unique ingredient, the composition can give a cured silicone rubber product having greatly improved resistance against dynamic fatigue.
