Features:

CBDA is a cycloaliphatic dianhydride and can produce colorless polymer films, especially when used in combination with fluorine containing co-monomers. It has a high melting point of over 300°C owing to its rigid structure. CBDA-based polyimide films have high modulus, lower flexibility, excellent optical transparency, and superior dielectric properties eg. decreased dielectric constant due to reduced intermolecular CTCs formation, the films are well-suited for advanced telecommunications hardware, like flexible OLED panels.

Applications:

High purity CBDA for R&D and commercial PI film industry
