1,2,4,5-cyclohexanetetracarboxylic dianhydride (HPMDA) CAS 2754-41-8
Aure Chemical Delivers Excellence in HPMDA
1,2,4,5-Cyclohexanetetracarboxylic dianhydride (HPMDA, CAS 2754-41-8) is a cycloaliphatic dianhydride widely used as a performance-modifying monomer in the synthesis of low-color, optically transparent, and functional polyimides. Owing to its alicyclic structure, HPMDA-based polymers exhibit excellent optical transparency, improved solubility, low moisture absorption, balanced thermal stability, and enhanced flexibility, making it particularly suitable for optical, dielectric, membrane, and advanced functional material applications.
