for Extrusion Silicone Rubber

1)Excellent transparency,physical and mechanical properties; 2)Very suitable for cables, sealing strips.

                                            Standard Silicone Rubber for Extrusion

 

This product could be put to basic processing after adding vulcanizator Double 2, 4. And it may not need second vulcanization when technical conditions properly controlled. It has excellent high and low temperature,electrical insulation, corona and arc resistance properties, which could be long-term used in temperature range from -60 to 200. It is suitable for different kinds of electric wire cable, and parts for electrical insulator.

Also this silicone rubber has excellent transparency, physical and mechanical properties, very suitable for cables, sealing strips and all kinds of transparent rubber tubes.
