กกกก PTFE
envelope gasket are type of static seal. It is composed of elastic
materials such as compressed non-asbestos sheet ,rubber,Ceramics,
etc., and a PTFE envelope cove
กกกกPTFE has
superior properties against chemical (not affected by all chemicals
except molten alkali metal and fluorine at elevated temperature)
and a wide working temperature range. (from จC180~260กๆ) the coefficient
of static and dynamic friction of PTFE are very low. PTFE is the
best of the กฐnon-stickกฑ materials. It has excellent weathering and
aging characteristics.
กกกกApplication:PTFE
envelope gasket is used to seal pipe flanges glass lined, PVC or
FRP. Low bolt torque effecting a seal and chemical compatibility
is a main characteristic of this type of gasket.
