Among anti-corrosion materials, polytetrafluoroethylene (PTFE) boasts unparalleled performance. With the exception of molten metals, elemental fluorine, and aromatic hydrocarbons, it resists corrosion from hydrochloric, sulfuric, and nitric acids (including aqua regia), organic acids, strong oxidizers, concentrated or dilute acids, alkaline solutions, and various organic solvents.
