Service Temperature:
Excellent resistance to continuous service temperatures up to 260° C and, for limited periods, even to higher temperatures:  the low temperature resistance of the product allows satisfactory performance at as low as - 200° C.
Chemical Resistance:
PTFE possesses a high inertness towards nearly all known chemicals.  It is only attacked by elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperature and pressures.
Solvents Resistance:
PTFE is insoluble in all solvents up to temperatures as high as 300° C (572° F).  Certain highly fluorinated oils
only swell and dissolve PTFE at temperatures close to the crystalline melting point.
