【 abstract 】

Is the abbreviation of pyromellitic dianhydride to PMDA, mainly used for the synthesis of polyimide, because the polyimide has excellent high heat resistance, acid-proof alkaline, excellent mechanical properties, electrical properties and dimension stability of characteristics, which is widely used in material performance demanding aviation, aerospace, microelectronics and atomic energy and other high-tech fields.

【 application 】

Pyromellitic dianhydride (PMDA) is one of the important raw material in organic synthesis industry, is developing new chemical materials and the basic materials of high value-added fine chemical products, mainly for the production of polyimide monomers, and also can be used as a curing agent of epoxy resin and polyester resin crosslinking agent, used in the manufacture of phthalocyanine blue dyes and some important derivatives, such as widely used.

Both pyromellitic dianhydride, also known as anhydride, has special molecular structure, can be used in the manufacture of heat resistance, electrical insulation, and chemical resistance of the material, the main purpose is as monomer of polyimide, and aromatic diamine synthesis polyimide was made by plastic, but for the purity of pyromellitic dianhydride requirements is very high, need more than 99%.

【 Application 1 】

It is used to make polyimide resin, high temperature resistant electric insulating paint, PVC plasticizer, synthetic resin crosslinking agent and epoxy resin curing agent, also used to make phthalocyanine blue dye, etc

【 Application 2 】

It is used in the manufacture of polyimide resins, which are used as raw materials for high temperature resistant electrical insulation paints. It can also be used to make epoxy resin curing agent and plasticizer, urea-formaldehyde resin stabilizer, phthalocyanine blue dye, corrosion inhibitor, instant binder, electronic photographic toner, etc.
