Silicone rubber composition for application as electrical insulation

摘要

A silicone rubber composition for application as electrical insulation that cures into a highly water-resistant silicone rubber that has excellent electrical properties and in particular has excellent high-voltage electrical insulation properties. The silicone rubber composition comprises (A) polyorganosiloxane, (B) surface-treated aluminum hydroxide powder surface treated with an organosilane or organosilazane, and (C) curing agent. Also, the composition afforded by the addition of 1 to 200 weight parts (D) microparticulate silica to components (A) to (C).
