Service Temperature
fluteck™ P8500 GL has a continuous service temperature range from -100° C (-148° F ) to 250° C (482° F). For limited periods, fluteck™ P8500 GL is capable of sustaining even higher temperatures. Additionally, fluteck™ P8500 GL is capable of satisfactory performance at temperatures down to -200° C (-328° F).
Chemical Resistance
fluteck™ P8500 GL is inert to nearly all known chemicals—except for elemental alkali metals, chlorine trifluoride, and elemental fluorine at high temperature and pressures. Glass fibers are chemically inert except for reactivity to hydrofluoric acid and strong bases.
Solvent Resistance
fluteck™ P8500 GL has insoluble properties in all solvents up to temperatures as high as 300° C (572° F). Certain highly fluorinated oils swell and dissolve PTFE at temperatures close to the crystalline melting point.
Food Contact
fluteck™ P8500 GL is suitable for food contact applications per FDA regulation 21 C.F.R. 177.1550.
