(Summary description)Polytetrafluoroethylene is the main variety of fluoroplastics. At present, the three main products of polytetrafluoroethylene sealing ring are suspension resin, dispersion resin and deep shrinkage dispersion liquid, which account for 50% - 60%, 20% - 35% and 10% - 20% of the consumption respectively. Suspension polytetrafluoroethylene is mainly used for sealing rings, gaskets, chemical pumps, valves, pipe fittings and equipment lining, electrical insulation parts and films, etc. Dispersion PTFE is mainly used for corrosion resistance, high temperature resistance, high dielectric wire and cable, chemical pipeline lining, etc. Polytetrafluoroethylene concentrated dispersion is mainly used in the fields of food, textile, papermaking, etc. With the continuous development of material application technology, the three shortcomings of PTFE material: cold flow, difficult welding, difficult melting processing are gradually being overcome, which makes it more widely used in optics, electronics, medicine, petrochemical and other fields.



Due to the defects of rubber, glass, metal alloy and other materials in corrosion resistance, it is difficult to meet the harsh conditions of temperature, pressure and chemical media coexisting environment, resulting in considerable losses. PTFE has become the main corrosion-resistant material in petroleum, chemical, textile and other industries due to its excellent corrosion resistance. Its specific applications include: conveying pipe, exhaust pipe and steam pipe for conveying corrosive gas, high-pressure oil pipe of rolling mill, high and low pressure pipeline of aircraft hydraulic system and cold pressing system, distillation tower, heat exchanger, lining of kettle, tower and tank, valve and other chemical equipment. The performance of seals has a great influence on the efficiency and performance of the whole machine. PTFE material has the characteristics of corrosion resistance, aging resistance, low friction coefficient, non stickiness, wide temperature range and good elasticity, which makes it very suitable for manufacturing seals with high corrosion resistance requirements and service temperature higher than 100 ℃. Such as machine, heat exchanger, high pressure vessel, large diameter vessel, valve, pump groove flange seal, glass reaction pot, plane flange, large diameter flange seal, shaft, piston rod, valve rod, worm gear pump, pull rod seal, etc.
