  • Applications

    2,2-Bis(4-(3,4-dicarboxyphenoxy)phenyl)propane dianhydride (CAS 38103-06-9) is primarily used as a dianhydride monomer to prepare high-performance polyimide resins, enabling heat-resistant, dimensionally stable coatings and films for electronics, aerospace, and automotive applications. It also serves as a precursor for prepregs and resin matrices in advanced composites and can function as a crosslinking/curing component in epoxy and other high-temperature resin systems, providing dielectric and insulating properties essential for electronic components.
