Because material such as rubber, glass, metal, alloy corrosion defects, it is difficult to meet the strict temperature, pressure and chemical coexistence environment, the resulting loss is very alarming. Polytetrafluoroethylene (PTFE) and polytetrafluoroethylene (PTFE) have become the main corrosion-resistant materials in petroleum, chemical and textile industries due to their excellent corrosion resistance. Its specific applications include: transportation corrosive gas pipeline, exhaust pipeline, steam pipeline, high pressure oil pipeline of steel rolling mill, aircraft hydraulic system and cold pressing high and low pressure pipeline system, distillation tower, heat exchanger, kettle, tower, tank, lining valve and other chemical equipment.

Sealing performance depends on the efficiency and performance of the whole machine and equipment. Polytetrafluoroethylene (PTFE) material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and viscosity. Its wide range of heat resistance and elasticity make it very suitable for seals with high corrosion resistance and temperature higher than 100 C. Such as machine, heat exchanger, pressure vessel, large diameter flange sealed container, valve, channel pump, glass reactor, flat flange, large diameter flange seal, shaft, piston rod, valve stem, worm gear oil pump, piston rod seal, etc.

Because of the unfavorable friction of some equipment lubrication, such as the situation that grease can be dissolved and failed by solvent or the need to avoid oil pollution in the field of industrial products such as papermaking, pharmaceuticals, food, textile and so on, filling PTFE material becomes the most ideal material for oil-free lubrication (direct load) of mechanical equipment parts. This is because the friction coefficient is the lowest solid material known. Specific purposes include chemical equipment, paper machinery, agricultural machinery bearings, used for piston rings, machine tool guideways, guide rings; civil engineering is widely used as bridges, tunnels, steel roof structures, bearing pedestals of large chemical pipelines, tanks, used as bridge bearings and reduced rotation.

Polytetrafluoroethylene gasket is a new sealing product and a breakthrough of new technology in the field of sealing at home and abroad. It has changed the traditional use of static sealing. It is a new concept of high-quality practical sealing belt. It is a comprehensive functional sealing product with broad significance. Polytetrafluoroethylene gasket, with its excellent performance, replaces polytetrafluoroethylene sealing belt and other sealing material sealing belt, and is more and more welcomed by various types of sealing industry and widely used. Polytetrafluoroethylene gaskets can effectively prevent leakage of various mechanical equipment, fuel tank end caps, cylinder end caps, gear box end caps, various pipeline flanges, devices, storage and transportation containers, towers, tanks, especially non-metallic industrial production facilities, and enhance sealing efficiency. It is an industrial production enterprise and related industries to solve gas, gearbox end caps, pipeline flanges, devices, storage and transportation containers, towers, tanks, and other industrial production facilities. The liquid medium "runs, rises, drips, leaks" is an effective tool to eradicate the leakage.
