Method of improving silicone rubber composition

摘要: A new method of producing a silicone rubber composition yields unique composition. When the is further mixed with extending filler and vulcanized, tensile strength vulcanized improved over that obtained when not produced following this invention. The mixes polydiorganosiloxane gum, treated reinforcing silica filler, portion hydroxylated organosilicon compound having an average from 1 to 20 percent by weight hydroxyl radicals 31 vinyl radicals; heating mixture; then cooling admixing another compound.
