Common grade HTV silicone rubber

    This product has good physical and mechanical properties and processability. This product can be divided into two sub-categories: rubber for molding and rubber for extrusion. The rubber for molding is vulcanized with 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane as vulcanizator, applicable to manufacturing of industrial miscellaneous parts such as keypads, sealing rings and sealing gaskets; and the rubber for extrusion is vulcanized with vulcanizator DCBP (Di-(2,4-dichlorobenzoyl) Peroxide), applicable to manufacturing of various electric wires, cables, hoses and tapes.
