BPADA Standard Grade for Polyimide Resin Synthesis
URL: /bpada-standard-grade-polyimide-resin
Product Summary
This standard grade of 4,4'-(4,4'-Isopropylidenediphenoxy)bis(phthalic anhydride) (BPADA) is a reliable monomer for general polyimide resin synthesis. It offers consistent quality for applications such as ion transport membranes, superhydrophobic aerogels, and other advanced materials where optical transparency and thermal stability are required. It has a melting point of 184-187 °C and appears as a white to light yellow crystalline powder.
Key Selling Points
- Consistent quality for general PI synthesis: Provides predictable performance in resin production.
- Versatile applications: Suitable for ion transport membranes and superhydrophobic aerogels due to chemical inertness and Lotus effect.
- High optical transparency: Allows production of transparent polyimide films.
- Reliable supply: Backed by ISO9001 quality management and SGS factory audit.

Materials and Structure
BPADA has a bisphenol A core with two phthalic anhydride groups, providing the structural basis for polyimides with high heat resistance and mechanical strength. The anhydride groups are moisture-sensitive, requiring dry storage.
Applications
- Polyimide resin synthesis
- Ion transport membranes
- Superhydrophobic aerogels
- High-temperature coatings
Customization
We can customize purity, packaging, and provide CDMO services for process optimization and scale-up.
Case Study
Our products have been used in innovative applications. For instance, a client developed superhydrophobic aerogels using our BPADA, achieving the Lotus effect for self-cleaning surfaces. This highlights the material's unique properties.
FAQ
