Pyromellitic dianhydride (PMDA) is an important raw material in the organic synthesis industry, as well as a basic raw material for the development of new chemical materials and high value-added fine chemical products. It is mainly used for the production of polyimide monomers, and can also be used as a Curing agent for epoxy resin and cross-linking agent for polyester resin, used in the manufacture of phthalocyanine blue dye and some important derivatives, etc., and has a wide range of uses. Pyromellitic dianhydride, also known as homoanhydride, has a special molecular structure and can be used to manufacture materials with heat resistance, electrical insulation and chemical resistance, among which the most important use is as a monolayer of polyimide. It is synthesized with aromatic diamine to obtain polyimide plastic, but the purity of pyromellitic dianhydride is very high, which needs to be more than 99%.
