PolyTetraFluoroEthylene (PTFE) is a man-made polymer that has particular applications in manufactured products because of the unique chemical properties of PTFE. PTFE is commonly known as Teflon (PTFE/Teflon was originally developed by the Du Pont Corporation). Key properties are: chemically inert, low coefficient of friction, non-adhesive, excellent electrical insulator and wide temperature range -110F (-73C) to +500F (+260C).
