Usage conditions apply
Teflon, a synthetic fluoropolymer of tetrafluoroethylene, was discovered, accidentally, by a chemist at DuPont in 1938. Kinetic Chemicals, an off-shoot of the firm, patented the new plastic in 1941, and registered the Teflon trademark in 1945. Wire and cable accounted for the biggest single use for Teflon.
This plenum cable sample is covered with Teflon. An inscription reads "Belden-E 89555...Made with DuPont Teflon Fluorocarbon Resin."
