Copolymerized Gum for HTV

Inquiry

The copolymerized gum for HTV (high temperature vulcanization) is a specialized copolymer comprised of methyl-(3,3,3-trifluoropropyl)siloxane, a small fraction of vinyl monomer, and other organic silicone components. This elastomer exhibits a high molecular weight and integrates the beneficial properties of both silicone rubber and fluororubber. As a result, it is ideally suited for use as sealing materials in demanding applications that require resistance to extreme temperatures—both high and low—as well as to oils, solvents, and other challenging substances.
