fluorhaltige

Fluorhaltige is a German term used to describe chemical substances that contain fluorine atoms in their molecular structure. The word functions as an attributive adjective, and it appears in contexts ranging from inorganic and organic chemistry to environmental science. In English-language discussions, the corresponding phrase is fluorine-containing or fluorinated compounds.

Fluorhaltige compounds exhibit distinctive properties due to the carbon–fluorine bond, one of the strongest single bonds in organic chemistry. They are typically highly chemically and thermally stable, resistant to oxidation, and have low reactivity. These characteristics give them uses in coatings, lubricants, refrigerants, electronics, pharmaceuticals, and specialty polymers. Common examples include fluorinated polymers such as PTFE (polytetrafluoroethylene), fluorinated solvents, and per- and polyfluoroalkyl substances (PFAS).

Environmental and health considerations: The persistence and potential for bioaccumulation of many fluorhaltige substances, particularly PFAS, have led to regulatory attention in many regions, including the EU and the US. Policies address manufacturing, use, labeling, and disposal, and encourage development of safer alternatives and life-cycle assessments. The term underscores a broad class of fluorine-containing materials, whose properties often drive their practicality but also raise sustainability questions.
