Abstract
A silicone rubber composition that does not foam or evolve an unpleasant odor during its cure and that cures into low-surface-tack, non-yellowing silicone rubber moldings comprises: PA1 (A) polydiorganosiloxane gum with the average component formula R.sub.a SiO.sub.(4-a)/2 where R represents substituted and unsubstituted monovalent hydrocarbon groups and a is from 1.9 to 2.1, PA1 (B) microparticulate silica, PA1 (C) bis(ortho-methylbenzoyl)peroxide, and PA1 (D) bis(para-methylbenzoyl)peroxide, wherein the component (C) to component (D) weight ratio is from 1:9 to 8:2.
