ptfe sealing flat gasket
When the temperature is below 185 ℃. 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 + 250 ℃ to 180 ℃ temperature long-term work).
