Standard grade HTV silicone rubber

IOTA Standard grade HTV silicone rubber

This product has flexible processability and comprehensive physical properties, excellent yellowing resistance and superior aging resistance at temperature of - 50 to 200℃. The rubber for molding is vulcanized with 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane as vulcanizator, applicable to manufacturing of various keypads for electronic & electric appliances, electrical insulations, automotive accessories, industrial & civil seal rings, miscellaneous parts and transparent pieces, etc. The rubber for extrusion is vulcanized with vulcanizator DCBP (Di-(2,4-dichlorobenzoyl) Peroxide), applicable to variousthermotolerant & cold resisting electric wires, cables and sheaths. This product is available as a milk-white translucent finished product, or compound with curing agent & pigment, or sliced product.
