Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]
In 1938, while attempting to make a new chlorofluorocarbon refrigerant, Plunkett's laboratory team discovered polytetrafluoroethylene (PTFE), better known as Teflon. In New York City in April 1986, Plunkett shared the story of his accidental discovery at the spring meeting of the American Chemical Society national meeting in the History of ...
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...
The modern non-stick pans were made using a coating of Teflon (polytetrafluoroethylene or PTFE). PTFE was invented serendipitously by Roy Plunkett in 1938, [3] [4] while working for a joint venture of the DuPont company. The substance was found to have several unique properties, including very good corrosion-resistance and the lowest ...
Teflon – Teflon was invented by a DuPont scientist in 1941 and used on frying pans from the 1950s; however, it has been applied by NASA to heat shields, space suits, and cargo hold liners. [55] Velcro – Velcro is a Swiss invention from the 1940s.
Play-Doh was originally called Rainbow Modeling Compound and used to clean wallpaper. A NJ nursery school teacher found it was fun to use as a toy.
Nylon is invented and patented by DuPont. [6] 1938: Nylon is first used for bristles in toothbrushes. It features at the 1939 World's Fair and is famously used in stockings in 1940. 1938: Polytetrafluoroethylene (commonly known as teflon), discovered by Roy Plunkett at DuPont. 1941
