WebMay 14, 2013 · "Melting" PTFE is not like melting most other polymers. [3] A fluid will wet a surface if it has a lower surface energy than the surface. PTFE has the lowest surface energies of all polymers (~ 19 dynes/cm 2), while the metals of the fry pan are hundreds if not thousands of dynes/cm 2. In other words, the PTFE can't help but stick to the metal. WebAug 13, 2024 · Polytetrafluoroethylene (PTFE) refers to the synthetic fluoropolymer derived from tetrafluoroethylene. It is a solid form of fluorocarbon and a compound with elevated …

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 … See more 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 tetrafluoroethylene gas … See more PTFE is produced by free-radical polymerization of tetrafluoroethylene. The net equation is n F2C=CF2 → … See more Processing PTFE can be difficult and expensive, because the high melting temperature, 327 °C (621 °F), is above the initial … See more 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 pyrolysis occurs at temperatures above 400 °C (752 °F). The main decomposition products are See more 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 (327 °C; 620 °F).
