Chemcal Resistance | 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. |
