Hot sale 2-Phenoxyethanol - Pyromellitic Dianhydride With CAS 89-32-7 – Unilong

The pyromellitic dianhydride (abbreviated as PMDA), which is mainly used for the synthesis of polyimide, because polyimide has excellent ultra-high heat resistance, acid and alkali resistance, excellent Because of its mechanical properties, electrical properties and dimensional stability, it is widely used in high-tech fields such as aviation, aerospace, microelectronics and atomic energy, which have strict requirements on material properties.

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%.
