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)
