Due to the corrosion defects of materials such as rubber, glass, metal, and alloy, it is difficult to meet the strict requirements of temperature, pressure, and chemical coexistence environment, resulting in astonishing losses. Polytetrafluoroethylene material has become a major corrosion-resistant material in industries such as petroleum, chemical, and textile due to its excellent corrosion resistance. Its specific applications include: transportation of corrosive gas pipelines, exhaust pipelines, steam pipelines, steel rolling mill high-pressure oil pipes, aircraft hydraulic systems and cold pressing high, medium and low pressure pipeline systems, distillation towers, heat exchangers, kettles, towers, tanks, lining valves and other chemical equipment.

The sealing performance is greatly influenced by the efficiency and performance of the entire machine equipment. Polytetrafluoroethylene material has corrosion resistance, aging resistance, low friction coefficient and viscosity, and a wide range of heat resistance and elasticity properties, making it very suitable for use in manufacturing seals that require high corrosion resistance and temperatures above 100 ℃. Such as machines, heat exchangers, pressure vessels, large-diameter flange sealed containers, valves, channel pumps, glass reactors, flat flanges, large-diameter flange seals, shafts, piston rods, valve stems, worm gear oil pumps, piston rod seals, and so on.

Due to unfavorable friction in equipment lubrication, such as in situations where grease can be dissolved by solvents and fail, or in industrial product fields such as papermaking, pharmaceuticals, food, textiles, etc., it is necessary to avoid oil contamination, making PTFE material the most ideal material for oil-free lubrication (direct load) of mechanical equipment parts. This is because the coefficient of friction is the lowest among known solid materials. Specific purposes include bearings for chemical equipment, paper machinery, agricultural machinery, used for piston rings, machine tool guides, and guide rings; In civil engineering, it is widely used as a bridge, tunnel, steel roof structure, large chemical pipeline for bearing seats, storage tanks, bridge bearings, and reduced rotation.

Polytetrafluoroethylene gasket is a new type of sealing product, which is a breakthrough in the sealing field of new technologies at home and abroad. Polytetrafluoroethylene gasket has changed the traditional use of static sealing and is a new concept of high-quality practical sealing tape. It is a comprehensive functional sealing product with broad significance. PTFE gaskets, with their excellent performance, are increasingly popular and widely used in various types of sealing industries, replacing PTFE sealing tapes and other sealing materials. Polytetrafluoroethylene gaskets can effectively prevent leaks in various mechanical equipment, oil tank end caps, cylinder end caps, gearbox end caps, various pipeline flanges, devices, storage and transportation containers, towers, tanks, especially non-metallic industrial production facilities, strengthen sealing efficiency, and are an effective tool for industrial production enterprises and related industries to solve the problems of gas and liquid media "running, emitting, dripping, and leaking" and eradicate leaks.
