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 ...
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] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .
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 ...
Polytetrafluoroethylene (commonly known as teflon), discovered by Roy Plunkett at DuPont. 1941: Polyethylene terephthalate (PET) is discovered at the Calico Printers' Association in Britain. Expanded polystyrene is first produced. [6] 1950: DuPont begin the manufacture of polyester. 1951
In 1945, DuPont commercialized PTFE as Teflon. They found that PTFE was resistant to corrosion, had low surface friction, and high heat resistance. [17] Tetrafluorethylene (TFE) can cyclize with a wide variety of compounds which led to the creation of a range of organofluorine compounds.
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.
The real-life story, which is in theaters now, follows Ohio attorney Rob Bilott (portrayed by Mark Ruffalo) as he steadfastly pursues a case against DuPont, the chemical company that created Teflon.
In 1938 Roy J. Plunket, a recent hire at DuPont, discovered polytetrafluoroethylene (or Teflon)—a fluoropolymer that led to the invention of synthetic rubber. [2] His early discovery led 3M scientists to develop the formula for Scotchgard, discovered by accident in 1953 when Joan Mullan—a 3M lab technician—spilled a few drops of a fluorochemical liquid destined for rubber jet fuel hoses ...
