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 .
In dissecting the cylinder, he found a mass of white solid in a quantity similar to that of the tetrafluoroethylene gas. It was determined that this material was a new-to-the-world polymer. Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic.

Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
The panels of the Eden Project are also made from ETFE, and the Tropical Islands have a 20,000 m 2 window made from this translucent material. Another key use of ETFE is for the covering of electrical and fiber-optic wiring used in high-stress, low-fume-toxicity and high-reliability situations.
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.
Chemours is the manufacturer of Teflon, the brand name of polytetrafluoroethylene (PTFE), known for its anti-stick properties. [4] It also produces titanium dioxide and refrigerant gases. [5] It is currently being sued by the PA Attorney General, for knowingly exposing the public to PFAS. [6]
