Full name also called PTFE gaskets or PTFE gasket abroad , gasket by PTFE rods, tubes, plate by the mechanical cutting or cutting into the flat gasket, V gaskets, piston rings, such as ball valve gasket has corrosion resistance,

Anti-aging and non-conductive and other good characteristics. Ptfe pH value 0 to 14 (molten alkali metals and fluorine, except under high temperature and high pressure. The in - between 100 ℃ ~ 100 ℃ can have good mechanical strength. 10 mpa pressure

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).

High temperature resistant, use the working temperature of 250 ℃. Good low temperature resistance, good mechanical toughness; Even if the temperature drops to 196 ℃, also can keep 5% elongation. Corrosion - to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents. Weather - to be the best in the plastic in aging life. High lubrication - is the lowest in the friction coefficient in solid materials. Don't stick - is the smallest, the surface tension of the solid material don't adhere to any material. Non-toxic, has a physiological inertia, long as artificial blood vessels and organs implanted without adverse reaction.
