China and the United States are the leading exporters of pyromellitic acid (CAS 89-05-4), accounting for the majority of global shipments, while Germany, South Korea, and India represent the largest importers. These countries consistently dominate trade flows, reflecting established supply chains in specialty chemical manufacturing and downstream applications such as polyimide production. Recent data indicates relative stability in export volumes from top suppliers, though fluctuations in Pyromellitic acid prices have accompanied shifts in regional demand—particularly increased procurement by Asian electronics manufacturers.
Pyromellitic acid (CAS 89-05-4) is a white to off-white crystalline solid at room temperature, odorless and non-volatile, with a high melting point of approximately 480 °C (decomposes). It is an aromatic tetracarboxylic acid and a key organic chemical intermediate. Industrially, it is primarily used in the synthesis of pyromellitic dianhydride (PMDA), a critical monomer for high-performance polyimide polymers. These polyimides are employed in demanding applications including flexible printed circuit boards, wire enamels, aerospace composites, and high-temperature adhesives and coatings.
Pyromellitic acid (PMA) is mainly used as intermediate for powder coating. Product Data Sheet
