DescriptionsHexafluorodianhydride (also known as 4,4 '- (hexafluoroisopropylidene) phthalic anhydride, 6FDA) is one of the six most widely used dianhydride monomers and is currently the most widely used Chemicalbook dianhydride monomer in colorless transparent polyimides. The glass transition temperature of polyimide synthesized from hexafluorodianhydride is usually above 300 ° C, and its mechanical and electrical properties are well balanced, making it the most representative fluorinated polyimide to date. Hexafluorodianhydride (6FDA) is an organic synthesis intermediate and pharmaceutical intermediate, which can be used in laboratory research and chemical and pharmaceutical synthesis processes, mainly as an electronic material polymer.
