Overview of PTFE

— PTFE (polytetrafluoroethylene) is ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. The commonly known brand name of PTFE-based formulas is Teflon® by Chemours, a spin-off from DuPont. PTFE has one of the lowest coefficients of friction of any solid, and is commonly used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon-fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery. It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268°C; -450°F), and good flexibility at temperatures above 194 K (-79°C; -110°F)
