PTFE envelope gasket is a kind of static seals. It is composed of elastic materials such as compressed asbestos sheet, rubber, ceramics, etc, ptfe envelope gasket, ptfe envelope gaskets and PTFE envelope cover.
PTFE has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature) and temperature (from:80~250 °C ) The coefficient of static and dynamic friction of PTFE are very low. PTFE is the best of the "non - stick" material. It has excellent weathering and aging characteristics.

Application:
PTFE envelope gasket, ptfe envelope gasket, ptfe envelope gaskets are used to seal pipe flange and joint of industrial machinery apparatus which is lined with rubber, plastic ceramics, graphite etc
