Transparentness and flexibility is needed for display parts of foldable devices. Fluorinated polyimide resin has these characteristics and suitable for foldable devises.
Daikin manufactures and sells the fluorine-containing monomer 6FDA which is one of the ingredients in fluorinated polyamide resin.
- Polyimide transparency
- Low dielectric constant of polyimide
By introducing fluorine into the polyimide using 6FDA, solubility and transparency in the visible light band, typically drawbacks of PI, are greatly improved.
