PTFE is a fluoropolymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. PTFE's low coefficient of friction makes it suitable for applications where sliding action of parts is needed: such as plain bearings, gears, and slide plates. In these applications, it performs significantly better than nylon and acetal; and is comparable to UHMW. PTFE however can be used over a far wider temperature range than these materials; -100?F to +400?F (-73?C to 204?C) and offers superior electrical insulation properties. Although its' mechanical properties are low compared to other engineering plastics, those properties can be enhanced through the use of additives such as Carbon, Graphite, Bronze, and Glass Fiber. The most commonly known brand name of PTFE-based formulas is Teflon? by Chemours
