Abstract (en)
A mixture of a first aluminum hydroxide surface treated with a silicon-containing compound and having a mean particle size of 5-20 mu m and a second aluminum hydroxide surface treated with a silicon-containing compound and having a mean particle size of 0.1-2.5 mu m is blended in a silicone rubber composition comprising an organopolysiloxane, finely divided silica, and an organic peroxide. The silicone rubber composition cures into silicone rubber having sufficiently improved properties to serve as high-voltage electrical insulators, even when exposed to air polluted conditions or rigorous weather conditions.
