teflon It is a key category of fluoroplastics, teflon At the present stage, the three major commodities of sealing rings supplied to the market are floating epoxy resin, dispersed epoxy resin and deeply reduced dispersed liquid, accounting for 50%~60%, 20%~35% and 10%~20% of the consumption respectively. The floating polytetrafluoroethylene is mainly used for sealing rings, gaskets, corrosion resistant pump, valves, pipe fittings and machine equipment linings, insulating parts and plastic films. Decentralization method teflon It is mainly used for heat-resistant and high dielectric cables and wires, chemical pipe lining, etc. teflon The concentrated and dispersed solution is mainly used for degumming coating, prepreg glass cloth, asbestos, etc. in food, textile, paper industry and other industries. Along with the continuous development trend of raw material application technology, the three major defects of PTFE materials: cold flow, difficult to weld, and difficult to melt process performance have been gradually eliminated, thus making its application prospects in electronic optics, electronic devices, medicine, petrochemical equipment, petroleum pipeline waterproof layer and other diverse industries broader.

Due to the shortcomings of raw materials such as vulcanized rubber, laminated glass, and metal aluminum alloy, they cannot meet the harsh natural environment where temperature, working pressure and organic chemicals coexist. The resulting damage is very shocking. PTFE has become a key raw material in the fields of crude oil, chemical plants, textiles and other fields due to its outstanding corrosion resistance. Its practical application includes: transportation pipes, exhaust pipes and steam pipes for corrosive steam bodies, hydraulic oil pipes of steel rolling machines, ordinary high, medium and low bottom pressure pipes of airport hydraulic transmission system and cold extrusion system software, rectification devices, heat exchangers, linings of kettles, towers and tanks, gate valves and other chemical machinery and equipment. hydraulic pressure Vinyl sealing tape The advantages and disadvantages of its characteristics are very harmful to the efficiency and characteristics of all mechanical equipment. PTFE material has the characteristics of low friction resistance, non viscosity, high temperature resistance, wide coverage, and good ductility, which makes it particularly suitable for the production of hydraulic seals with high manufacturing requirements and application temperatures higher than 100 ℃. For example, hydraulic seals for equipment, heat exchangers, pressure vessels, large-diameter vessels, gate valves, and grooved flange plates of pumps, hydraulic seals for laminated glass reaction pots, plan flange plates, large-diameter flange plates, and hydraulic seals for shafts, hydraulic cylinders, gate valve rods, worm gear pumps, and support rods.
