® - Roy Plunkett
PTFE or polytetrafluoroethylene was
discovered on April 6, 1938 by Dr. Roy Plunkett at the DuPont research
laboratories (Jackson Laboratory in New Jersey). Plunkett was working with
gases related to Freon® refrigerants when
upon checking a frozen, compressed sample of tetrafluoroethylene, he and
his associates discovered that the sample had polymerized spontaneously
into a white, waxy solid to form polytetrafluoroethylene or PTFE.
PTFE was first marketed under the
DuPont Teflon ® trademark in 1945. The molecular weight of Teflon can
exceed 30,000,000, making it one of the largest molecules known. The surface
is so slippery, virtually nothing sticks to it or is absorbed by it. No
wonder Teflon was choosen to be used on non-stick cooking pans.
Chemical Description of Teflon
Teflon is a colorless, odorless
powder, a fluoroplastic with many properties which give an increasingly
wide range of uses.

on an accident and invented one of the best known and most widely used
polymers of all time: Teflon.
