Abstract
The present invention provides a silica-containing heat curing silicone rubber compound composition which can be produced safely and hardly suffers from inclusion of foreign substances. More specifically, when (A) 100 parts by weight of a polyorganosiloxane base polymer and (B) 1 to 100 parts by weight of a reinforcing silica are mixed together, (C) 0.05 to 80 ppm of an ionic liquid whose anionic component is bis(trifluoromethanesulfonyl)imide is added thereto.
