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 ...
It had been accidentally invented in 1938 by DuPont chemist Roy Plunkett, as a by-product of chlorofluorocarbon refrigerant research. [ 21 ] [ 22 ] [ 23 ] After further industrial experience with General Mills Company back in Minneapolis and Spencer Kellogg & Sons, Inc. in Buffalo , Renfrew returned west in 1959 to his alma mater in Moscow to ...
Richard Gurley Drew (June 22, 1899 – December 14, 1980) was an American inventor who worked for Johnson and Johnson, Permacel Co., and 3M in St. Paul, Minnesota, where he invented masking tape and cellophane tape.
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
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
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 .
He had accidentally invented polytetrafluorethylene (PTFE), a saturated fluorocarbon polymer—the "first compound in the family of Perfluorinated compounds (PFCs), "to be marketed commercially."(Lyons 2007) [15] It took ten years of research before polytetrafluorethylene (PTFE) was introduced under its trade name Teflon, where it became known ...
Marc Grégoire (January 15, 1906 - January 10, 1996 [1]) was an inventor of PTFE (Teflon) coated non-stick pans. [2] He was an ONERA engineer at the time of the invention. [3] In one version of the story, he devised a method to apply Teflon to an aluminum mould, to assist the removal of glass fibre fishing rods from the mould. [3]
