Product Introduction:

Hexafluorodianhydride (6-FDA), also known as 4,4′-(hexafluoroisopropylidene)diphthalic anhydride, has the chemical formula C19H6F6O6.

6FDA, white crystal or powder, is one of the six most widely used dianhydride monomers, and is currently the most used dianhydride monomer in colorless and transparent polyimide.

The glass transition temperature of polyimide synthesized by 6-FDA is usually above 300°C, and the mechanical properties and electrical properties are well balanced.

4,4′-(hexafluoroisopropylidene)diphthalic anhydride is still the most representative fluorine-containing polyimide so far.

Product Usage:

6-FDA (6FDA) is mainly used in epoxy resin, polyamide resin and polyimide resin.

6-FDA is an organic synthesis intermediate and a pharmaceutical intermediate, which can be used in the laboratory research and development process and the chemical and pharmaceutical synthesis process, mainly as an electronic material polymer.

The hygroscopicity and dielectric constant of the fluorine-containing polyimide synthesized by 4,4-Diphthalic Anhydride are lower than those synthesized by other dianhydrides.

In addition, the fluorine-containing polyimide is soluble and is a necessary dianhydride monomer for producing colorless and transparent polyimide.

Product Performance and Advantages:

Low dielectric constant

  • The dielectric constant of ordinary polyimide is about 3.4, but after adding 6FDA, its dielectric constant can be reduced to 2.5.
  • The low dielectric constant of 6-FDA brings about a reduction in signal delay and loss, which is of great value in electrical applications.

Transparency and controllable refractive index

  • Because polyimide is slightly yellowish or brown, adding 6-FDA can make it transparent.
  • And according to how much 6FDA is added, its refractive index (refractive index) can be controlled. These properties play a great role in the application of optical components.

Chemical and thermal stability

  • After the introduction of fluorine atoms, due to the strong negative charge of fluorine atoms, the chemical and thermal stability of polyimide will be improved, so that the product can work under special chemistry or temperature.

Lubricity

  • Because of the low polarity of fluorine atoms, the fluorine-containing polyimide has low surface free energy, smooth surface and low friction.

Thermal oxidation resistance

  • The fluorine-containing polyimide material synthesized with 6FDA has very good thermal oxidation resistance, high temperature hot melt resistance and radiation resistance, and is the preferred structural material in the aerospace industry.
