In 1936, he was hired as a research chemist by E.I. du Pont de Nemours and Company at its Jackson Laboratory in Deepwater, New Jersey. [ 1 ] In 1938, while attempting to make a new chlorofluorocarbon refrigerant, Plunkett's laboratory team discovered polytetrafluoroethylene (PTFE), better known as Teflon.
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 ...
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
Robert W. Gore (April 15, 1937 – September 17, 2020) was an American engineer and scientist, inventor and businessman. Gore led his family's company, W. L. Gore & Associates, in developing applications of polytetrafluoroethylene (PTFE) ranging from computer cables to medical equipment to the outer layer of space suits.
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 ...
