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.
