Application

3,3',4,4'-Benzophenonetetracarboxylic dianhydride is a white crystalline powder that serves as a fundamental monomer in the production of polyimide materials. Its significance extends to its role as an intermediate in polycondensation processes, facilitating the creation of various plastic products and fine chemicals within industrial domains. Notably, BTDA finds applications in the synthesis of polyimides, the preparation of cellulose acetate hydrogels, the curing of epoxy powder coatings, the development of nanocomposite films, and in the formation of polyimide/copolymer dielectric layers for advanced organic field-effect transistor memory devices. As BTDA is exclusively manufactured and managed under tightly controlled industrial conditions, the risk to consumers remains minimal. Comprehensive studies and evaluations provide insight into its environmental effects, ecotoxicology, and hazardous properties.
