Product Description

Standard grade high temperature resistant rubber

This product is specially designed for the products working at high temperature. It is manufactured with special formula and process, without changing the unique cold resistance of silicone rubber and the excellent physical and mechanical properties, covering a wide range of applications. The three series are slightly different in the appearance: the common type is milk-white, translucent or white; the standard type is light yellow or maroon and the fumed type is light yellow. This product can be used at 250ºC for a long time and can withstand an instant temperature of 300ºC. It is applicable to production of various temperature resistant seals, rubber rolls and sealing joint strips, etc.
