- As the global demand for high-performance materials continues to rise, the purification process and green synthesis technology of high-purity pyromellitic acid dipropylene (PMDA), the core of polyoxymethylene, have become the key to industry breakthroughs.
- As a professional supplier, JAMMARK INTERNATIONAL TRADINGE has always focused on the research and development of PMDA products with a purity of ≥99.5%.
- By optimizing catalytic oxidation and continuous thermoplastic processes, it has achieved a catalyst recovery rate of >95% and significantly reduced three-emission waste products, providing customers in electronics, aviation and other fields with simplified, low-reliability solutions.
High-purity Pyromellitic Dianhydride(99.5%)Main Applications
High-Performance Polyimide Synthesis: Used in the production of heat-resistant polyimide resins and films, widely applied in electronic insulation materials, aerospace, and advanced engineering fields.
Epoxy Resin Curing Agent: Provides a high glass transition temperature (Tg up to 300 °C) and excellent mechanical properties, ideal for high-performance coatings and adhesives.
Electronics and Fine Chemicals: Serves as a key raw material for phthalocyanine blue pigments, corrosion inhibitors, and other specialty chemicals.
Product Advantages
With 99.5% high purity, low free acid, and minimal impurities, this product ensures efficient polymerization and enables the production of high molecular weight polymers. It significantly improves thermal stability and mechanical strength in end-use applications.
Pyromellitic dianhydride packaging
Packaging materials and sealing
- Double-layer packaging: Use plastic film as the inner layer and cardboard barrels as the outer layer to isolate air and moisture.
- Strict sealing: The packaging must be completely sealed to prevent PMDA from being exposed to moist air, otherwise it will quickly hydrolyze into pyromellitic acid
Storage environment requirements
- Cool and Dry: Store in a cool, well-ventilated warehouse, away from fire, heat and direct sunlight.
- Moisture-proof measures: The humidity in the warehouse needs to be strictly controlled. It is recommended to use desiccant to assist in moisture-proofing
As a manufacturer specializing in the production of high-purity pyromellitic dianhydride (PMDA), JAMMARK INTERNATIONAL TRADINGE strictly follows international chemical safety standards in the export process, ensuring product stability and personnel safety throughout the entire process from operational protection to transportation management.
