PTFE also called ‘Polytetrafluoroethylene’‘Teflon’and so on. It is made of tetrafluorethylene by polymerization of polymer compounds, its structure is 

simplified as -[-CF2-CF2 -] N -, has excellent chemical stability, corrosion resistance, is one of the best corrosion resistance materials in the world today, in 

addition to molten metal sodium and liquid fluorine, can withstand all other chemicals, boiling in aqua rega can not change, It is widely used in all kinds of 

occasions requiring acid and alkali resistance and organic solvents. It has sealing, high lubrication, non-adhesive, electrical insulation and good aging resistance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). Teflon itself is not toxic to humans.

Its production has solved many problems in chemical, petroleum, pharmaceutical and other fields. Ptfe seals, gaskets, gaskets. Ptfe seals, gaskets, sealing 

gaskets are made of suspended polymerized PTFE resin moulding process. Compared with other plastics, polytetrafluoroethylene has the characteristics of 

chemical resistance, it has been widely used as a sealing material and filling material.

Used as engineering plastics, can be made into PTFE pipe, rod, belt, plate, film, etc. Generally USED IN high performance requirements of corrosion resistant 

pipelines, containers, pumps, valves and radars, high-frequency communication equipment, radio equipment, etc. The dispersing liquid can be used as an 

insulating impregnating liquid of various materials and an antiseptic layer on the surface of metal, glass and pottery. All kinds of PTFE ring, PTFE gasket, PTFE 

root are widely used in all kinds of anti-corrosion pipe flange seal. In addition, can also be used for drawing, PTFE fiber - flon (foreign trade name teflon).

At present, all kinds of plastic king products have played a pivotal role in the fields of chemical industry, machinery, electronics, electrical appliances, aerospace, environmental protection and Bridges.

Polytetrafluoroethylene (PTFE) use conditions industry chemical, petrochemical, oil refining, chlor-alkali, acid, phosphate fertilizer, pharmaceutical, chemical 

fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, iron and steel, atomic energy and polymer filtration materials, high purity product production (such as ion film electrolysis), viscous material transport and operation, Food, beverage and other processing and production sectors with highly stringent 

hygiene requirements.
