PTFE was discovered in 1938 by chemist Roy Planctes (Roy J. Plunkett) in DuPont's Jackson Laboratory in New Jersey, USA : When he tried to produce a new CFC refrigerant, Tetrafluoroethylene was polymerized in a high-pressure storage container ( The iron in the inner wall of the container becomes the catalyst for polymerization. DuPont obtained its patent in 1941 and registered trademarks in 1944 with the name of "teflon". Subsequently, DuPont also developed a series of products, including Teflon, in addition to teflon® Teflon resin; AF (amorphous fluorine polymer), Teflon; FEP (ethylene fluoride propylene resin), Teflon; FFR (fluorinated polymer foam resin), Teflon; NXT (fluorinated polymer resin), Teflon.
PFA (PFOS) and so on. In 1954, the French engineer, Mark Grey (Marc Gregoire) 's wife, Camelot (Colette), felt that her husband's non-stick material Teflon (Teflon), which was used to prevent knotting on the fishing line, would have a good effect if it could be used on a frying pan. The "Non-stick pot" that saved countless modern housewives was born.
