Polyimide Raw Materials
- We supply transparent polyimide, a key monomer used for cover windows and substrates in foldable and flexible displays, to major domestic and international companies.
- We have successfully localized key raw materials such as 6-FDA and TFMB, which previously relied heavily on imports, and we pride ourselves on having the world's highest quality.
- Through continuous collaboration with our clients, we are conducting research and development on various polyimide-related materials, striving tirelessly towards global excellence.
