피로멜리트산 이무수물 PMDA CAS 89-32-7

BLIT Chemical Pyromellitic Dianhydride (PMDA) is an organic compound with two anhydride functional groups attached to a benzene ring. It is a white crystalline solid widely used in the manufacture of polyimide resins, adhesives, and coatings. PMDA plays a significant role in the electronics and aerospace industries due to its high-temperature resistance and excellent electrical properties.

PMDA is also a precursor in the production of high-performance plastics used in microwave circuits, semiconductor devices, and automotive parts.

High thermal stability: decomposition temperature is higher than 500°C, suitable for high temperature applications.

Excellent mechanical properties: high strength, high modulus, suitable for structural materials.

Chemical inertness: solvent, acid and alkali resistant, suitable for harsh environments.
