CBDA
Cyclobutane tetracarboxylic dianhydride
CAS Number: 4415-87-6
Synonyms:
- 1,2,3,4-Cyclobutanetetracarboxylic dianhydride
- Cyclobutane-1,2,3,4-tetracarboxylic dianhydride
CBDA is a cycloaliphatic dianhydride and can produce low-color 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 and superior dielectric properties well-suited for 5G-enabled telecommunications hardware.
