English Name: 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride
CAS Number: 1107-00-2
| use | Hexafluorodihydride (6FDA) is an organic synthesis intermediate and pharmaceutical intermediate that can be used in laboratory research and development processes and chemical and pharmaceutical synthesis processes, mainly as polymers for electronic materials. |
| Product performance | a. Low dielectric constant. The dielectric constant of ordinary polyimide is about 3.4, and after the addition of 6FDA, its dielectric constant can be reduced to 2.5. Low dielectric constants result in reduced signal delay and loss, which is of great value in electrical applications. b. Transparency and controllable refractive index. Because polyimide is slightly yellowish or brown, after adding 6FDA, it can become transparent, and according to how much 6FDA is added, its refractive index (refractiveindex) can be controlled, and these properties have a great role in optical Chemicalbook component applications. c. Chemical and thermal stability. After the introduction of fluorine atoms, because of the strong negative electrical properties of fluorine atoms, the chemical and thermal stability of polyimides will be improved. This allows the product to operate under special chemical or temperature conditions. d. Lubricity. Because of the low polarity of the fluorine atom, the fluorine-containing polyimide has a very low surface free energy, the surface is smooth, and the friction is small. e. The fluorine-containing polyimide material synthesized with 6FDA has very good resistance to thermal oxidation, high temperature hot melt and radiation resistance, and is the preferred structural material for the aerospace industry |
