Abstract:
A silicone rubber composition comprising(A) 100 parts by weight of an organopolysiloxane containing at least two alkenyl radicals in a molecule, represented by the following average compositional formula (1): RnSiO(4âˆ’n)/2â€ƒâ€ƒ(1) wherein R which may be the same or different is a substituted or unsubstituted monovalent hydrocarbon radical and n is a positive number of 1.98 to 2.02, said organopolysiloxane having a degree of polymerization of at least 100, (B) 0.5 to 50 parts by weight of an organopolysiloxane or organosilane represented by the following general formula (2): R2O(SiR12O)mR2â€ƒâ€ƒ(2) wherein R1 which may be the same or different is a substituted or unsubstituted monovalent hydrocarbon radical, R2 is hydrogen or an alkyl radical, and m is a positive number of 1 to 50, (C) 5 to 100 parts by weight of reinforcing silica having a specific surface area of at least 50 m2/g, and (D) 0.1 to 10 parts by weight of an alkali metal salt of phosphoric acid.
