ABSTRACT:
A silicone rubber composition is obtained by blending (A) 100 parts by weight of an organopolysiloxane composition of the addition reaction curing type with (B) about 30-400 parts by weight of aluminum hydroxide which has been surface treated with an organosilane or organosilazane substantially free of an aliphatic unsaturated group or a partial hydrolyzate thereof so that the aluminum hydroxide has 0.01-2% by weight of carbon affixed thereto. The composition maintains silicone rubber properties even though it is loaded with large amounts of aluminum hydroxide. It cures into a silicone rubber having improved high-voltage electrical insulating properties and thus suited for use as high-voltage electrical insulators.
