Teflon is the brand name of a compound discovered by Roy J. Plunkett (1910-1994) of DuPont in 1938 and introduced as a commercial product in 1946. Teflon is polytetrafluoroethene (PTFE).Teflon is also used as the trade name for a polymer with similar properties, perfluoroalkoxy polymer resin (PFA). :Teflon is the plastic with the lowest coefficient of friction. It is also used as a non-stick coating for pans and other cookware. Teflon is very unreactive, and so is often used in containers and pipework for reactive chemicals. Its melting point is 327 Â°C.
