Our Isophthalic Acid (PIA) is a high-purity, white crystalline flake or powder with the molecular formula C₆H₄(COOH)₂. It is an aromatic dicarboxylic acid isomer, where the two carboxyl groups are in the meta-position on the benzene ring. This unique molecular structure imparts distinct properties compared to its isomers, terephthalic acid (TPA) and ortho-phthalic acid, making it a crucial modifying monomer for enhancing the performance of polymers, resins, and coatings. It offers superior thermal stability, chemical resistance, and mechanical properties.
