Use Of Pyromellitic dianhydride
1.Pyromellitic dianhydride is used in the manufacture of polyimide resins, which are used as raw materials for high temperature electrical insulating varnishes
2.PMDA can be used as a synthetic raw material for epoxy resin curing agents, stabilizers and dyes.
3.PMDA can used in the preparation of phthalocyanine blue dyes
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. PMDA, 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%.
