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 °C.
Teflon is sometimes said to be a spin-off from the US space program with more down-to-earth applications, but actually its first significant use was in the Manhattan Project, as a material to contain highly-reactive uranium hexafluoride. It was first sold commercially in 1946.
Teflon has been supplemented with another DuPont product, Silverstone , a three-coat fluoropolymerA fluoropolymer is a polymer that contains atoms of fluorine. They are characterized by an unusual resistance to solvents, acids, and bases. Fluoropolymers were discovered serendipitously in 1938 by Dr. He was working on freon (for the DuPont corporation) system that produces a more durable finish than Teflon.
