BisAPAF is a polyimide monomer. A material that simultaneously meets the requirements of high temperature resistance (260℃), low dielectric constant (Dk = 2.8), and strong corrosion resistance (98% sulfuric acid).

It is used as a raw material for heat-resistant polymers. Particularly, it can serve as a raw material for preparing special polymer electronic materials of fluorinated polyimides. It can be used in the production of high-performance photosensitive resins. As a cross-linking agent for fluorine-based rubbers, it endows rubber products with excellent resistance to compression set, chemical corrosion, and thermal stability.
