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 theconfiguration 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 highreactivity during polymerization. In the application of display materials, such as alignment films for liquidcrystal-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 excellence flexibility, and therefore it is agood candidate for flexible substrate applications.

BDA

Meso-Butane-1,2,3,4-tetracarboxylic dianhydride (BDA) has good dielectric properties and flexibilitywhich makes it widely used in polyimide resins or polyamic acid resins.
