What is the Pyromellitic Dianhydride?

Pyromellitic Dianhydride is White powder, while it's Molecular Formula is C10H2O6. White powder Pyromellitic dianhydride is used as a monomer in the preparation of polyimide polymers such as kapton; thermoplastics such as polyesters, polyethers, plasticizers, and expoxy resins. It is involved in the preparation of high performance coatings due to its mechanical, thermal and oxidative stability properties. It acts as a curing agent for epoxy resins which find application in adhesives, coatings and molding powders. As an intermediate, it plays an important role in polyimide based materials like printed circuit boards, tape automated bonding and magnetic wire insulation.

What is the CAS number for Pyromellitic Dianhydride?

The CAS number of Pyromellitic Dianhydride is 89-32-7.

What is Pyromellitic Dianhydride (89-32-7) used for?

Pyromellitic dianhydride (PMDA) is a key monomer used in the synthesis of high-performance polyimides and poly(ester-imide)s, contributing to their thermal stability, mechanical strength, and solubility in polar aprotic solvents. In this study, PMDA was employed to develop optically active poly(ester-imide)s incorporating L-alanine, which exhibited enhanced processability and maintained desirable thermal properties, making them suitable for advanced applications in industries such as microelectronics and aerospace.
