PTFE Sheets & Rods exhibit astonishing chemical resistance. 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 stands for PolyTetraFluoroEthylene, it is a fluorocarbon-based polymer. The Teflon® brand of PTFE is resin manufactured only by DuPont. Several other manufacturers make their own brands of PTFE which can often be used as substitute material. Professional Plastics offers various brands of PTFE including Teflon®, Dyneon and Daiken, but it's important to note that mechanical PTFE is a reprocessed grade that may contain a variety of brands in the overall blend. The mechanical properties and purity of Mechanical Grade PTFE may also be lower than Virgin Grade PTFE. Mechanical Grade PTFE is supplied without warrantee or any gaurantees regarding minimal properties. Customers requiring material certifications and traceabilty should consider Virgin PTFE made from Dyneon or Daiken resins, or other premium Teflon® Brand compounds such as Teflon® 7A, 7C, 8A or 9B.
PTFE's overall mechanical properties are lower than most thermoplastics, but can be used over a wide temperature range of -100°F to +400°F (-73°C to 204°C). Mechanical properties may often enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze. PTFE 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.
