Pyromellitic Dianhydride 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.

Specification:

Application:

Polyimide Resins:PMDA is most commonly used as a precursor in the synthesis of polyimide resins, which are employed in high-temperature applications, aerospace, and electronics.

Coatings and Adhesives:Used to produce high-performance coatings that offer thermal stability, electrical insulation, and resistance to wear and tear. It is also used in adhesives that are required to perform under extreme conditions.

Electronics and Aerospace:PMDA-based polyimide materials are commonly used in flexible circuits, semiconductor devices, and insulating films in electronic components,Such as DuPont Kapton。

Polyester Resins:PMDA is used in the manufacture of polyester resins, which are employed in various composite materials for automotive and construction applications,Such as Kevlar analogs.

Usage Guidelines:

Handling: Use in a well-ventilated area with appropriate personal protective equipment (PPE), such as gloves, goggles, and a face shield.

Storage: Keep in a cool, dry place, away from moisture and incompatible materials. Store in tightly closed containers.

Processing Temperature: Heat and handle PMDA in accordance with established safety guidelines to prevent decomposition and ensure high-quality resin production.
