Polytetrafluoroethylene is the main variety of fluoroplastics

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.

The products made of polytetrafluoroethylene are widely used

The products made of polytetrafluoroethylene, whether in the field of chemical industry or in the field of machinery, or in the field of electronics and military industry, or even in the field of environmental protection, have a certain role and influence. Moreover, they have many advantages. In addition to the familiar characteristics of wide temperature range and corrosion resistance, they also have good weather resistance, Therefore, tempering furnace can ensure a very long aging life. In addition, it has no toxic problem in use. Because of physiological inertia, it can be used as raw material for artificial blood vessels or organ products, and there will be no adverse reactions after long-term implantation into the human body. In addition, it has no adhesion, and its own polytetrafluoroethylene is in the solid material, It belongs to a kind of small surface tension, so there is no need to worry about the above problems. It is also necessary to add that the friction coefficient of PTFE is relatively low, so it has the characteristics of high lubrication
