General purpose grade HTV silicone rubber

This product has superior physical, mechanical and electrical properties, and excellent 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, and is widely used to manufacture various keypads, industrial & civil silicone rubber products, sealing elements and miscellaneous parts; it is also applicable to general electric components. The rubber for extrusion is vulcanized with vulcanizator DCBP (Di-(2,4-dichlorobenzoyl) Peroxide), applicable to various silicone rubber tubes, shaped rubber strips and foam rubber strips, etc. This product is available as a ivory subtranslucent finished product, or compound with curing agent & pigment, or sliced product.
