ABSTRACT:
In a silicone rubber composition comprising (A) an organopolysiloxane of the organic peroxide curing type or addition reaction curing type, (B) a curing agent, and (C) non-spherical silica fine powder, (D) a mixture of 50-95% by weight of spherical fused silica having a mean particle size of 7-40 .mu.m and 50-5% by weight of spherical fused silica having a mean particle size of 0.1-6.5 .mu.m is blended in an amount of 100-900 parts by weight per 100 parts by weight of components (A) and (B) combined. The composition has a low viscosity and high fluidity despite high loading and heat cures into a product having low coefficients of shrinkage and expansion and low water absorption.
