CHENGDU FLUORINCHEM NEW MATERIAL CO., LTD.

General Purpose Silicone Rubber for Extrusion

This product could be put into basic processing after adding vulcanizator “Double 2, 4” . And it may not need second vulcanization when technical conditions properly controlled. The formed product has the following properties: very good high and low temperature  resistance, corona and arc resistance, and electric  insulation.  It is suitable for different kinds of electric wire and cable, jacket rubber tubes and parts for electrical insulator, heat-resistant seals, irregular shaped and foam strips.
