Product Name: 1,2,3,4-Cyclobutanetetracarboxylic Dianhydride
CAS No.: 4415-87-6
Molecular Formula: C₈H₄O₆
Product Overview
1,2,3,4-Cyclobutanetetracarboxylic Dianhydride (CBDA) is a high-performance tetrafunctional dianhydride monomer featuring a rigid cyclobutane structure. It serves as a key raw material for synthesizing specialty polyimides (PI), polyamic acids, and other high-performance polymers. Polyimides derived from CBDA are renowned for their exceptional transparency, high thermal resistance, low dielectric constant, and low birefringence. Leveraging advanced production technology, UIV Chem has achieved large-scale production of this product with high purity, catering to the growing demands of high-end electronic and optical material industries.
