Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [citation needed] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]
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 (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.
Nafion is a brand name for a sulfonated tetrafluoroethylene based fluoropolymer-copolymer synthesized in 1962 by Dr. Donald J. Connolly at the DuPont Experimental Station in Wilmington Delaware (U.S. Patent 3,282,875). Additional work on the polymer family was performed in the late 1960s by Dr. Walther Grot of DuPont. [1]
DuPont filed its initial Form 10 with the SEC in December 2014 and announced that the new company would be called "The Chemours Company." [ 8 ] The name is a portmanteau of the words chemical and Nemours, a nod to DuPont's full name, E. I. du Pont de Nemours & Co.
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 March 1981, DuPont sent a pathologist and a birth defects expert to review the 3M data Bailey had read about in the locker room. They concluded that “the study was valid” and that “the observed fetal eye defects were due to C8,” according to internal DuPont documents.
