Abstract
Silicone rubber compositions useful for high-voltage insulators, and which cure to give silicone rubbers having a low combustibility, are addition-crosslinkable or peroxide-crosslinkable silicone rubber compositions containing aluminum hydroxide as filler, with the uncrosslinked composition having a storage stability which is improved compared to the prior art and improved processing properties by including an acid, base, or a compound which liberates an acid or base upon heating. These improved properties are achieved both with surface-treated aluminum hydroxide and with untreated aluminum hydroxide.
