Polytetrafluoroethylene, better referred to as PTFE or Teflon, was accidentally invented by Roy Plunkett of Kinetic Chemicals in New Jersey in 1938. Even though Plunkett was attempting to make a new chlorofluorocarbon (CFC) refrigerant, the perfluorethylene polymerized in its pressurized storage container, using the iron from the inside of the container acting as a catalyst. Kinetic Chemicals patented it in 1941 and registered the Teflon trademark in 1945, which was a joint venture in between DuPont and Common Motors.

In chemistry, polytetrafluoroethylene (PTFE) is really a synthetic fluoropolymer of tetrafluoroethylene that finds quite a few applications. PTFE is mostly well known by the DuPont brand name Teflon. PTFE is often a fluorocarbon solid, as it's a high molecular weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic, meaning substances containing water are expelled because of the differences in electrical charges, to be far more precise because of the electronegativity of fluorine.

Teflon fluoropolymer items are utilised in industrial and commercial applications, including cabling solutions, pharmaceutical, biopharma manufacturing and semiconductor manufacturing. For instance, PTFE is utilized as a non stick coating for pans and other cookware. It really is very non reactive, partly because of the strength of carbon fluorine bonds, and so it really is frequently employed in containers and pipework for reactive and corrosive chemicals. Where utilized as a lubricant, PTFE reduces friction, put on and energy consumption of machinery.

DuPont Teflon resins are developed to fulfill the requirements of a vast array of insulated wire and cable merchandise. This is an perfect choice for insulation and jacketing applications exactly where low flammability, exceptional dielectric properties, high resistance, chemical inertness, and thermal cycling capabilities are required. This is why the usage of this materials in electrical devices and server centers is becoming a common so as to avoid any kind of accidents. This is why this materials is considered among the biggest innovations of the twentieth century.
