Enflo can skive sheet .001″ thick to .250″ in Virgin PTFE and .010″ to .250″ in reprocessed. We can mold sheet up to 7″ thick in Virgin and ENFLON ® (filled) PTFE.
Yes. Enflo can skive up to 72″ wide in thicknesses of .010″ to .250″ thick.
PTFE can stick to another surface by using a chemical process called etching on one side or two sides. The etching is brown in color and when an epoxy is applied to the etched side it will adhere to another surface.
Etched one side is material prepared for gluing. Pressure sensitive tape is etched material with an adhesive backing paper.
Virgin PTFE has better physical properties and is a good electrical insulator. Virgin PTFE is FDA approved. Reprocessed PTFE is recycled PTFE processed into skived sheet and extruded rod. Both Virgin and reprocessed PTFE are 100% PTFE.
PTFE materials are essentially chemically inert. They are affected only by molten alkali metals, fluorine and chlorine trifluoride at elevated temperatures and pressures.
The maximum service temperature is 500°F.
25% Glass fill increases wear resistance. Carbon and graphite exhibit good initial wear and better thermal conductivity. Bronze fill has better wear and creep resistance than glass fill.
PTFE stands for PolyTetraFluoroEthylene, a synthetic fluoropolymer of tetrafluoroethylene with an enormous number of applications. PolyTetraFluoroEthylene is the chemical term for the polymer (C2F4)n.
