When
the temperature is below **5℃. PTFE gaskets gasket will become
fragile. Pure PTFE gaskets gasket sealing products is a kind of
clean, not any contact with the material to its formation
pollution, can be widely used in food, medicine and other
industries. Ptfe
is composed of tetrafluoroethylene by polymerization of polymer
compounds, it has excellent chemical stability, corrosion
resistance, corrosion resistance in the world today is one of the
best materials, in addition to the molten metal liquid and sodium
fluoride, ingeneral, all other chemicals in aqua regia boil also
doesn\'t change, is widely applied to various needs the operation
condition of the resistance to acid and alkali and organic
solvent), sealing, high lubrication is not sticky, electric
insulation and good aging resistance, large span of heat-resistant
(at + **0℃to
**0℃temperature long-term
work).
