Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the best-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the … Zobacz więcej Polytetrafluoroethylene was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the By 1948, … Zobacz więcej PTFE is produced by free-radical polymerization of tetrafluoroethylene. The net equation is n F2C=CF2 → −(F2C−CF2)n− Because tetrafluoroethylene can explosively decompose to [O3SO−OSO3] … Zobacz więcej Wire insulation, electronics The major application of PTFE, consuming about 50% of production, is for the insulation of wiring in aerospace and computer applications (e.g. hookup wire, coaxial cables). This application exploits the fact that … Zobacz więcej Trifluoroacetate Sodium trifluoroacetate and the similar compound chlorodifluoroacetate can both be generated when PTFE undergoes thermolysis, … Zobacz więcej PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2200 kg/m and a melting point of 600 K … Zobacz więcej Processing PTFE can be difficult and expensive, because the high melting temperature, 327 °C (621 °F), is above the initial … Zobacz więcej While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate at temperatures of about 260 °C (500 °F), it decomposes above 350 °C (662 °F), and Zobacz więcej WitrynaNatural Rubber Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree.
