U.S. Plastic Corp.® carries a complete line of PTFE sheet, rod and shapes.  PTFE is a low friction fluoropolymer with outstanding chemical and weathering resistance. The working temp range is -20° F to 500° F. PTFE has the lowest coefficient of any solid and it has no slip-stick characteristics; static and dynamic coefficients are equal. Nothing sticks with any strength of PTFE to unheated surfaces. Both virgin and mechanical grades are UV stabilized. Virgin material meets FDA standards and is USDA approved.
