CBDA

Cyclobutane-1,2-3,4-tetracarboxylic dianhydride (CBDA) is an alicyclic dianhydride.
Based on our unique photochemical reaction, we can develop the core structure of cyclobutane, and the configuration of CBDA can be determined to be cis-trans-cis.
CBDA is widely used as a raw material for polyimide resins or polyamic acid resins because of its high reactivity during polymerization. In the application of display materials, such as alignment films for liquid crystal display devices, CBDA provides excellent electrical properties such as high VHR (Voltage Holding Rate)
and low RDC (residual DC Voltage Measurement).
Furthermore, polymers made of CBDA offer good transparency and excellent flexibility, and therefore it is a good candidate for flexible substrate applications.
