essential information:
Hexafluorodianhydride (6FDA) is an important organic synthesis intermediate and pharmaceutical intermediate, and is currently one of the most promising dianhydride monomers, mainly used as a raw material for electronic material production. The introduction of hexafluorodianhydride into the production of polyimide has led to a qualitative leap in the properties of polyimide, including dielectric constant, dielectric loss, transparency, relative thermal stability, and radiation resistance. Enable downstream products to be applied in high-energy fields such as semiconductors and aerospace. In recent years, the industrial use has mainly been as the main raw material for colorless transparent polyimide (CPI).
6FDA refers to 4,4 '- (hexafluoroisopropenyl) phthalic anhydride, also known as hexafluorodianhydride. The chemical formula is C19H6F6O6.
