4,4'-(Hexafluoroisopropylidene) diphthalic anhydride is one of the six most widely used dianhydride monomers and the most widely used dianhydride monomer in colorless transparent polyimide.By six fluorine dianhydride and the glass transition temperature of polyimide usually above 300 ° C, mechanical properties and electrical balance is good, so far, is still the most representative of the fluorinated polyimide.
. 4,4'-(Hexafluoroisopropylidene) diphthalic anhydride is also named as 2,2-Bis(3,4-anhydrodicarboxyphenyl)hexafluoropropane;6FDA.
4,4'-(Hexafluoroisopropylidene) diphthalic anhydride has been supplying from UCHEM in large quantity with competitive price.
