Product Description

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 200ºC. 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.
