Silicone rubber compositions for high-voltage electrical insulators

摘要

A silicone rubber composition comprising (A) an organopolysiloxane having at least two aliphatic unsaturated hydrocarbon groups attached to a silicon atom, (B) finely divided silica, (C) aluminum hydroxide surface treated with silazanes, (D) an organohydrogenpolysiloxane having at least two hydrogen atoms attached to a silicon atom, and (E) a platinum catalyst is suitable for use as a high-voltage electrical insulator. The silicone rubber has durable high-voltage electrical insulating properties and is firmly bondable to core materials.
