The scientific name of Teflon is Polytetrafluorothene (Polytetrafluoroethene), the English abbreviation is PTFE, (commonly known as "Plastic King, Hara"), the brand name is Teflon?, in China, due to the pronunciation, "Teflon "This trademark is also called "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", etc., all of which are transliterations of "Teflon".
The products of this material are generally called "non-stick coating"; it is a synthetic polymer material that uses fluorine to replace all the hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents.
At the same time, PTFE has the characteristics of high temperature resistance. Its friction coefficient is extremely low, so it can not only act as lubrication, but also become an ideal coating for non-stick pots and the inner layer of water pipes.
Extended information
Polytetrafluoroethylene was invented in 1938 by chemist Dr. Roy J. Plunkett at DuPont’s Jackson Laboratory in New Jersey, USA. An unexpected discovery?: When he was trying to make a new chlorofluorocarbon refrigerant, tetrafluoroethylene polymerized in a high-pressure storage container (the iron in the inner wall of the container became a catalyst for the polymerization reaction).
DuPont obtained its patent in 1941 and registered a trademark under the name "Teflon" in 1944. Subsequently, DuPont developed a series of products in addition to Teflon? polytetrafluoroethylene resin.
Including Teflon; AF (amorphous fluoropolymer), Teflon; FEP (fluorinated ethylene propylene resin), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (fluoropolymer resin) , Teflon; PFA (perfluoroalkoxy resin), etc.
In 1954, Colette, the wife of French engineer Marc Gregoire, had a sudden idea that Teflon, the non-stick material her husband used to coat fishing lines to prevent knots, was If Teflon can be used on a frying pan, it will be very effective. The "non-stick pan" that saved countless modern housewives was born.
