4,4’-(Hexafluoroisopropylidene)diphthalic Powder Description
Hexafluorodianhydride (also known as 6FDA) is one of the six most widely used dianhydride monomers, and it is also currently a colorless transparent polyamide. The largest dianhydride monomer is used in imines. The glass transition temperature of polyimide synthesized from hexafluorodianhydride is usually above 300℃, and the mechanical and electrical properties are well balanced. So far, it is still the most representative fluorine-containing polyimide.
