This product has good processability. The rubber for molding is vulcanized with 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane as vulcanizator, applicable to manufacturing of common silicone rubber products and miscellaneous parts, common silicone rubber keypads, especially pigmented products; and the rubber for extrusion is vulcanized with vulcanizator DCBP (Di-(2,4-dichlorobenzoyl) Peroxide), applicable to manufacturing of low-end miscellaneous extruded silicone rubber products.
