Details:
Hexafluoradianhydride (also known as 4,4'-(hexafluorisopropyl) diphthalic anhydride, 6FDA) is one of the six most widely used dianhydride monomers, and also the most widely used Chemicalbook dianhydride monomer in colorless transparent polyimide. Polyimide synthesized from hexafluoradianhydride usually has a glass transition temperature above 300°C and good mechanical and electrical properties. So far, it is still the most representative fluorinated polyimide.
Product performance:A. Low dielectric constant. The permittivity of ordinary polyimide is about 3.4, but with the addition of 6FDA, its permittivity can be reduced to 2.5. Low permittivity leads to a reduction in signal delay and loss, which is of great value in electrical applications. B. Transparency and controllable refractive index. Because polyimide is slightly yellow or brown, after adding 6FDA, it can become transparent, and can control its refractiveindex according to how much 6FDA is added, these properties have a great role in optical Chemicalbook applications. C. Chemical and thermal stability. The chemical and thermal stability of polyimide will be improved due to the strong electronegativity of fluorine atom. Allows the product to work under special chemical or temperature conditions. D. lubricity. Because of the low polarity of fluorine atoms, fluorinated polyimides have very low surface free energy, smooth surface and low friction. E. Fluorinated polyimide materials synthesized with 6FDA have excellent thermal oxidation resistance, high temperature thermal fusion and radiation resistance, and are the preferred structural materials for aerospace industry
