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]
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 ...
They are now used in products including waterproof fabric such as Nylon, yoga pants, carpets, shampoo, feminine hygiene products, mobile phone screens, wall paint, furniture, adhesives, food packaging, heat-resistant non-stick cooking surfaces such as Teflon, [4] firefighting foam, and the insulation of electrical wire.
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.
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 ...
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 ...
