The structure and properties of porous poly(tetrafluoroethylene ...

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 … 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 → −(F2C−CF2)n− Because tetrafluoroethylene can explosively decompose to tetrafluoromethane (CF4) … See more Wire insulation, electronics The major application of PTFE, consuming about 50% of production, is for the insulation of wiring in aerospace and computer … See more Trifluoroacetate Sodium trifluoroacetate and the similar compound chlorodifluoroacetate can both be generated when … 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). It maintains high … See more Processing PTFE can be difficult and expensive, because the high melting temperature, 327 °C (621 °F), is above the initial decomposition temperature, 200 °C (392 °F). Even when molten, PTFE does not flow due to its exceedingly high melt-viscosity. The … 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 WebThe mechanical properties were evaluated and compared with a rabbit aorta and expanded poly-tetrafluoroethylene (ePTFE). The PLCL scaffolds had circumferentially stronger tensile stress than the rabbit aorta and ePTFE graft, and its longitudinal stress was similar to a rabbit aorta but weaker than ePTFE. green lake county land conservation
