Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally discovered the compound in 1938. [4]
Tetrafluoroethylene (TFE) is a fluorocarbon with the chemical formula C 2 F 4. It is the simplest perfluorinated alkene. This gaseous species is used primarily in the industrial preparation of fluoropolymers. It was first reported as "dicarbon tetrafluoride" in 1890. [2]
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. Aircraft, spacecraft and motorsport wiring are primary examples. Some small cross-section wires like the wire used for the wire-wrap technique are coated with ETFE.
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 ...
The wonder chemical responsible for Teflon’s great utility is known as PFOA, one of the first compounds of its type. Tightly bonded carbon and fluorine atoms give PFOA toughness, hinting at its ...
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
That specific chemical compound is called perfluorooctanoic acid, or PFOA. Here's what you need to know. Sure, we've all said, "Eh, everything causes cancer," but the risks of PFOA are not over ...
