Modified HTV silicone rubber
This product is
manufactured with high-quality raw materials and has three series. Its special
formula are designed for cable accessories and the molded or extruded products
requiring some strength in ordinary industries. The product is corona-resistant
and arc-resistant, with stable weatherability and electrical insulating
property. It has high transparency and physical & mechanical properties.
The rubber for molding is vulcanized with
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane as vulcanizing agent and the rubber
for extrusion is vulcanized with vulcanizing agent DCBP
(Di-(2,4-dichlorobenzoyl) Peroxide), particularly applicable to manufacturing
of various wall bushings, cable accessories, electrical insulation products and
other industrial products.
