High Temperature Resistant Silicone Rubber

This product has excellent heat and high temperature resistant properties. It adopted special ingredients and technical processing, which makes it own better high temperature and heat resistance properties comparing with common silicone rubber. Among them, milky whitetranslucent or white color is available for common series with its temperature resistance up to 280; light yellow or brown red color for standard series is available with high temperature resistance up to 300.This product is suitable for making various kinds of high temperature resistant gasketrollerpartssealing  strip and so on.
