Red Color Virgin PTFE Washer Gasket Size 3mm Thick 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.
