Abstract
A silicone rubber composition is obtained by blending (A) 100 parts by weight of an organopolysiloxane composition of the organic peroxide or addition reaction curing type, with (B) 30-400 parts by weight of aluminum hydroxide which has been surface treated so as to bear 1.0.times.10.sup.-6 to 2.0.times.10.sup.-4 mol/gram of vinyl groups. The composition does not lose rubber strength even though it is loaded with large amounts of aluminum hydroxide. It cures into a silicone rubber having satisfactory physical properties and improved high-voltage electrical insulating properties and thus suited for use as high-voltage electrical insulators.
