Customized White 100% PTFE Material Envelope Gasket/Washer Sealing Thickness1-6mm for Sealing fitting
PTFE envelope gasket is a kind of static seals.It is composed of elastic materials such as compressed asbestos sheet,rubber,ceramics,etc. 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 - 180ºC ~ +250ºC)The coefficient of static and dynamic friction of PTFE are every low.PTFE is the best of the "non-stick"material. It has excellent anti weathering and aging characteristics.
