PTFE (PolyTetraFluoroEthylene), it is a fluorocarbon-based polymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE (polytetrafluoroethylene) sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. The Teflon® brand of PTFE is resin manufactured only by DuPont (see links of left-side of page). Several other manufacturers make their own brands of PTFE which are commonly available in the marketplace. Professional Plastics offers a wide variety of PTFE materials including Teflon®.
PTFE's mechanical properties are low compared to other plastics, and can be used over a wide temperature range of -100°F to +400°F (-73°C to 204°C). Mechanical properties are often enhanced by adding fillers (see paragraph below). It has excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is very dense and cannot be processed by melting. PTFE must be compressed and sintered to form useful shapes. Virgin Grade PTFE Sheets and PTFE Rods are available from this page.
