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.
