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. We offers various brands of PTFE including Teflon®, Dyneon and Daiken, but mechanical PTFE (as sold here) 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 DuPont Teflon® specialty grades such as Teflon 7A, Teflon 7C, Teflon 8A or Teflon 9B - Teflon® specialty grades are available as a custom order only and are priced higher than Generic Virgin PTFE Shapes - Lead-Time Will Apply.

FEATURES AND BENEFITS
Benefits of PTFE Sheets & Rods
Lowest coefficient of friction of any known material.
Operates up to 500F and has Superior Chemical Resistance
Excellent Insulating properties
Limitations: Very Low Compressive & Tensile Strength (Virgin PTFE is better).
Mechanical PTFE is produced in a maximum thickness of 0.250" - for thicker sheets, use VIRGIN PTFE
Mechanical PTFE is NOT for high-purity applications - Made from Recycled PTFE resin.
I bought both the Mechanical and Virgin grade sheets for testing purposes. Both looked good, but the Virgin grade definitely had higher physical properties and appeared to be slightly cleaner. For future orders, I am using the Virgin grade because the price is very similar.
