Product Details

     Teflon is known as "King of Plastics", "Teflon".It is a polymerized polymer compound of tetrafluoroethylene with excellent chemical stability and corrosion resistance. It is one of the best materials for corrosion resistance in the world. It can resist all other chemicals except molten metal sodium and liquid fluorine. Boiling in King Water does not change, widely used in a variety of acid-alkali and organic solvents), sealing, high lubricating non-viscosity, electrical insulation and good anti-aging endurance, Excellent temperature tolerance, ie ability to work for a long period of time from 250 ℃ to-180 ℃. PTFE itself is not toxic to human beings, but ammonium perfluorooctanoate (PFOA), one of the raw materials used in the production process, is considered to be carcinogenic at a temperature of -20 ~ 250 ℃ (-4 + 482F), allowing sudden heat to be quenched, or alternating cold and heat. Pressure -0.1v 6.4Mpa (total negative pressure to 64kgf/cm2) (Fullvacum to 64kgf / cm2)

Packing,storage,Transportation

1.PTFE is packed in double layer PVC bags inside and in hard circular barrels outside. On the barrel,there should be attached label and quality certificate, on which there are brand,trademark,executive criterion,type,grade,lot No. and net content,pack date,checker and packer.         2.PTFE should be stored in clean dry warehouse to pervent from dust,moisture,etc,foreign matters.       3.The products are transported according to non-dangerous products.Heat,moisture,freezing and strong shock should be avoided during transportation.Over-bumpiness and compression is apt to make the resin bind together.                                      

 

       PTFE seals, gaskets, gaskets. PTFE seals, gaskets, gaskets are made of suspension polymerized polytetrafluoroethylene resin molded. Polytetrafluoroethylene (PTFE) has been widely used as sealing material and filling material for its chemical corrosion resistance compared with other plastics. Used as engineering plastics, can be made into PTFE tubes, rods, belts, plates, films, etc. Generally used in corrosion resistant pipes, containers, pumps, valves and radar, high frequency communication equipment, radio equipment and so on. Dispersions can be used as insulating dipping fluid and metal, glass, pottery surface anticorrosion coating. All kinds of polytetrafluorine ring, polytetrafluorine gasket, polytetrafluorine disk are widely used in all kinds of anticorrosive pipe flange seal. In addition, it can also be used for drawing, polytetrafluoroethylene fiber-fluorofibe


      At present, all kinds of PTFE products have played an important role in the fields of chemical, mechanical, electronic, electrical, military, aerospace, environmental protection and bridges. Mainly used in coating, lubricating oil, engineering plastics, plastic modification, cosmetics, rubber, medical equipment and other fields. Polytetrafluoroethylene (PTFE) conditions for use Chemical, Petrochemical, Refining, chlor-alkali, Acid making, Phosphate Fertilizer, Pharmaceutical, pesticides, Chemical Fiber, dyeing, Coking, Gas, Organic Synthesis, Nonferrous smelting, Iron and Steel, Nuclear energy and high-purity products (such as ion membrane electrolysis), viscous materials transport and operation, hygiene requirements of highly stringent food, beverage processing and production departments
