Material Notes:

Properties/Improved compression and wear resistanceExcellent chemical stabilityBetter thermal conductivityExcellent resistance to continuous service temperatures up to 260Â°C, and, for limited periods, even to higher temperaturesChemical 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 temperatures and pressures.Solvents resistance: PTFE is insoluble in all solvents up to temperatures as high as 300Â°C. Certain highly fluorinated oils only swell and dissolve PTFE close to the crystalline melting point.Information provided by Isoflon.
