Products Description
BPADA - Incorporates an isopropyl structure, with excellent solubility. It fundamentally resolves the issues of deep color and poor melting property in traditional PI materials, being colorless, transparent, and impact-resistant. It is suitable for optical-grade transparent PI films and high-transparency flexible displays.
BPADA is used as a di-anhydride monomer to synthesize polyimide and polyetherimide resins that possess high thermal stability, mechanical strength and optical transparency for electronic, flexible display and aerospace applications.
The colorless transparent polyimide film made from it features good light transmittance and low CTE, ideal for flexible substrates of foldable screens

FAQ
Q: What polymer is mainly synthesized from BPADA?
A: It is mainly used to prepare meltable polyimide (PI) and colorless transparent CPI polyimide.
Q: What advantages does BPADA-based PI have compared with ordinary PI?
A: Traditional PI is difficult to melt-process. BPADA-based polyimide has flexible ether bonds for melt molding while maintaining high heat resistance and high light transmittance.
Q: What precautions for storage?
A: Keep sealed, dry and moisture-proof. Its dianhydride groups will hydrolyze when exposed to water vapor.
Q: Is the PI film made of BPADA high temperature resistant?
A: Yes. BPADA-based polyimide has excellent heat resistance and can withstand high temperature in electronic manufacturing.
