U.S. Plastic Corporation PTFE Discs/Cap Liners 60183

These are white PTFE discs for weighing pans and many other uses. They are .010" thick. PTFE has a virtually universal chemical inertness; of commercial chemicals, only molten alkali metals and gaseous fluorine at high temps and pressure attack PTFE. The working temp range is -20F - 500F. It has the lowest coefficient of any solid. It has no slip-stick characteristics; static and dynamic coefficients are equal. Nothing sticks with any strength to unheated surfaces. UV stabilized. Virgin material meets FDA standards and is USDA approved.
