polytef ptfe has a series of excellent performance: high temperature resistance -- long-term service temperature of 200~260 degrees, low temperature resistance -- softness at -100 degrees. corrosion resistance - resistance to aqua and all organic solvents; weather resistance - optimal aging life of plastics; high lubrication - with the minimum friction coefficient of plastics (0.04); non-viscous - having the minimum surface tension of a solid material without adhering to any substance; non-toxic - physiological inert; excellent electrical properties, ideal grade c insulation material, a thick layer of newspaper can block 1500v of high pressure; it's smoother than ice. polytetrafluoroethylene materials are widely used in such important sectors as defence industry, atomic energy, petroleum, radio, electric power machinery and chemical industry. products: polytef tetrafluoroethylene rod, pipe, plate, turning plate. polytef is a polymer of tetrafluoroethylene. the abbreviation is ptfe. the formula is cf3(cf2cf2)ncf plug. it was discovered in the late 1930s that industrial production went into the 1940s. properties of polytetrafluoroethylene are relatively large in molecular weight, low in the hundreds of thousands, high in more than 10 million, and generally in the millions (polymerization degree in 104 order of magnitude, while polyethylene is only in 103). general crystallinity is 90 ~ 95%, melting temperature is 327 ~ 342 ℃. in polytetrafluoethylene molecules, cf2 units are arranged in a serrated shape. since fluorine atom has a larger radius than hydrogen, the adjacent cf2 units cannot be fully cross-oriented in the trans-crossing direction, but form a helical twisted chain. fluorine atoms cover almost the entire surface of the polymer chain. this molecular structure explains the various properties of ptfe. temperature is lower than the 19 ℃, form a spiral 13/6; phase transition in 19 ℃, molecular slightly untied, form a spiral 15/7.
