Everything about Roy Plunkett totally explained
Roy J. Plunkett (
1910-06-26 -
1994-05-12 In
1936 he was hired as a research chemist by
E.I. du Pont de Nemours and Company at their Jackson Laboratory in
Deepwater, New Jersey. On
April 6,
1938 Plunkett checked a frozen, compressed 100 pound (45 kg) container of
tetrafluoroethylene, used in chlorofluorocarbon refrigerant production. When he opened the container to remove an amount for chlorination (using
hydrochloric acid), Plunkett discovered that nothing came out. When he checked to see why, he discovered that a white powder had formed which didn't adhere to the container. The tetra
fluoroethylene in the container had
polymerized into
Polytetrafluoroethylene (
Teflon), a waxy solid with amazing properties such as resistance to
corrosion, low surface
friction, and high
heat resistance.
He was the chief chemist involved in the production of the gasoline additive
Tetra-ethyl lead at DuPont's Chambers Works from
1939 to
1952. After that he directed
Freon production at DuPont before retiring in
1975. He was inducted to the Plastics Hall of Fame in
1973 and the Inventors Hall of Fame in
1985. Plunkett died on
May 12,
1994 at the age of 84.
