Pure Tetrafluoride Gasket is called PTFE gasket or Teflon (Teflon, Teflon) gasket. It is mechanically turned or cut by Teflon rod, tube and plate. The flat gasket, V-shaped gasket, piston ring, ball valve gasket, etc. can also be molded into a molded PTFE gasket by high-temperature vulcanization.
At temperatures below -185 ° C, the Teflon gasket becomes brittle; above 200 ° C it creeps. Pure PTFE gasket is a clean sealing product that does not pollute any substances it contacts. It can be widely used in food, medicine and other industries.
1. Strong acid resistance. Strong alkali, almost resistant to all chemical media, except for molten alkali metals and elemental fluorine.
2. Excellent insulation performance, good weathering resistance and weather resistance. PTFE does not absorb water, is not affected by oxygen and ultraviolet rays, and has good weather resistance. After exposure for 3 years outdoors, the tensile strength remains almost unchanged, and only the elongation rate decreases.
3. Low friction coefficient, easy to bond, easy to install and disassemble
4. The product is clean and can be used for sealing parts that are not allowed to be contaminated by food, medicine, etc.
5. High mechanical strength, good turning performance and easy processing into different sealing products.
Industries used in PTFE gaskets: chemical, petrochemical, refining, chlor-alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high purity products (Eg: Ion membrane electrolysis), the transportation and operation of viscous materials, and the processing and production departments of food and beverages with strict requirements for hygiene.
Equipment for PTFE gaskets: Sealing parts for flange joints such as pipes, valves, pumps, pressure vessels, heat ex-changers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc.
