Abstract:
The present invention is a silicone rubber composition characterized by containing (A) 100 parts by mass of an organopolysiloxane having a degree of polymerization of 100 or higher and having two or more alkenyl groups bonded to silicon atoms per molecule, (B) 10-100 parts by mass of reinforcing silica having a specific surface area by the BET method of 50 m2/g or higher, (C) 0.01-10 parts by mass of a lanthanum oxide-cerium oxide solid solution, and (D) 0.1-10 parts by mass of a curing catalyst. There is thereby provided a silicone rubber composition that yields silicone rubber having exceptional heat resistance that undergoes little change in physical properties even when exposed to high temperatures.
