As for the corrosion defects of materials such as rubber, glass, metal and alloy, it is difficult to meet the strict environment of temperature, pressure and chemical substances, and the resulting losses are very amazing. And polytetrafluoroethylene materials have become the main corrosion-resistant materials in petroleum, chemical, textile and other industries because of their excellent corrosion resistance. Its specific applications include: transportation of corrosive gas pipelines, exhaust pipelines, steam pipelines, high-pressure oil pipes of steel mills, aircraft hydraulic systems and cold pressing high, medium and low-pressure piping systems, rectification towers, heat exchangers, kettles, towers, tanks, lined valves and other chemical equipment.

The sealing performance depends on the efficiency and performance of the whole machine and equipment. Polytetrafluoroethylene material has corrosion resistance, aging resistance, low friction coefficient and viscosity. Its wide range of heat resistance and elastic properties make it very suitable for manufacturing seals that need high corrosion resistance and temperature higher than 100 ℃. Such as machines, heat exchangers, pressure vessels, vessels with large diameter flange seals, valves, channel pumps, glass reactors, flat flanges, large diameter flange seals, shafts, piston rods, valve stems, worm gear oil pumps, piston rod seals, etc.

Due to the unfavorable friction, some equipment lubrication, such as the situation that the grease can be dissolved and failed by the solvent, or the need to avoid oil contamination in the fields of papermaking, pharmaceutical, food, textile and other industrial products, makes the filled PTFE material become 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 among known materials. Specific purposes include chemical equipment, paper machinery, agricultural machinery bearings, used for piston rings, machine tool guide rails, guide rings; In civil engineering, it is widely used as large chemical pipelines and storage tanks for bridges, tunnels, steel roof truss structures, bearing pedestals, bridge bearings and reduced rotation.

Polytetrafluoroethylene gasket is a new 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. It is a new concept of high-quality practical sealing belt, and a comprehensive functional sealing product with broad significance. Polytetrafluoroethylene gasket, with its excellent performance, replaces the sealing belt of polytetrafluoroethylene sealing belt and other sealing materials. It is more and more popular and widely used in various types of sealing industries. Polytetrafluoroethylene gasket can effectively eliminate the leakage of all kinds of mechanical equipment, oil tank end covers, cylinder end covers, gear box end covers, various pipe flanges, devices, storage and transportation containers, towers, tanks, especially non-metallic and other industrial production facilities, and strengthen the sealing efficiency. It is an effective tool for industrial production enterprises and related industries to solve the "escape, emission, dripping and leakage" of gas and liquid media and eradicate the leakage.
