Mechanical Grade PTFE is supplied without warrantee or any gaurantees regarding minimal properties. The mechanical properties and purity of Mechanical Grade PTFE may also be lower than Virgin Grade PTFE. We offers various brands of PTFE, but mechanical grade PTFE (as sold here) is a reprocessed grade that may contain a variety of brands in the overall blend. Several other manufacturers make their own brands of PTFE which can often be used as substitute material. PTFE is a self-lubricating material that provides a low friction coefficient, and is ideally suited for the manufacture of corrosion-resistant gaskets & seals. PTFE Sheets & Rods exhibit astonishing chemical resistance. Chemours® PTFE is a registered trademark of Chemours Customers requiring material certifications and traceabilty should consider VIRGIN PTFE made from Dyneon or Daiken resins, or Chemours® PTFE specialty grades such as Chemours® 7A, Chemours® 7C, Chemours® 8A or Chemours® 9B - Chemours® PTFE specialty grades are available as a custom order only and are priced higher than Generic Virgin PTFE Shapes - Lead-Time Will Apply. The most commonly known brand name of PTFE-based formulas is Teflon® by Chemours 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. PTFE however can be used over a far wider temperature range than these materials -100☏ to +400☏ (-73☌ to 204☌) and offers superior electrical insulation properties. In these applications, it performs significantly better than nylon and acetal and is comparable to UHMW. 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. 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 is a fluoropolymer that exhibits astonishing chemical resistance and ultra high-purity.
