6-fda CAS 1107-00-2


6FDA is one of the six most widely used dianhydride monomers, and it is also the most used dianhydride monomer in colorless transparent polyimide. The glass transition temperature of polyimide synthesized from hexafluorodianhydride is usually above 300 °C, and the mechanical properties and electrical properties are well balanced. So far, it is still the most representative fluorine-containing polyimide.
