PTFE is chemically inert & unaffected by all known chemicals except molten or dissolved alkali metals-Sodium, Potassium, Rubidium, Cesium, Francium & Fluorine Gas.
certain fluorine compounds & complexes at elevated temperatures.
Filled PTFE has interior chemical resistance because of the presence of the
particular filler.
