| Description:PTFE is widely used in many fields, such as chemical, petroleum, pharmaceutical, food and so on, because of its excellent corrosion resistance, aging resistance, insulation, cleanness and so on. It is called "the king of plastics". PolyPTFE has strong corrosion resistance. Only a few elements in molten alkali metals and high temperature and high pressure elements can play a role in it. PTFE does not absorb water, is not affected by oxygen and ultraviolet, and has good weatherability. After exposure for 3 years, the tensile strength remains almost unchanged, and the elongation only decreases. Because tetrafluoro easily produces cold flow and creep under pressure and high temperature, it is very suitable for the sealing parts of low or low temperature or middle temperature corrosion or not allowed to be polluted. TetrafluoroPTFE has good mechanical strength between -100 and 100 degrees C, and can be processed into different shapes of PTFE products.
Main varieties: pump valve fittings, valve seat gaskets, mechanical parts, tower packings, die blanks, bearing rack compensates, seals, wear-resistant sleeves, O rings, etc.
Performance characteristics of PTFE parts:
1., strong acid resistant, strong alkali, almost all chemical media, except for molten alkali metals and elemental fluorine.
2. insulation performance has good weatherability and weatherability.
3., the friction coefficient is low, it is not easy to bond, easy to install and disassemble.
4., the product is clean, it can be used for food, medicine and other parts that are not allowed to be contaminated.
5., high mechanical strength, good turning performance, easy to be processed into different sealing products.
The 5. line expansion coefficient is low, and it is easy to produce creep or stress relaxation when it is subjected to cold flow and high temperature, which is not suitable for high temperature and high pressure parts.
Industry: chemical, petrochemical, oil refining, chlor alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, nonferrous smelting, steel, atomic energy and high purity product production (such as ion membrane electrolysis), viscous material transport and operation, hygienic requirements of highly strict food and beverage, etc. Industry and production department.
The use of equipment: Machinable lining, complex workpiece, three way, four links, elbow and other pipe fittings, wide turning plate, chemical containers and so on.
