China and India are the leading exporters of N-Phenylmaleimide (CAS 941-69-5), collectively accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. N-Phenylmaleimide prices have remained relatively stable amid steady cross-border flows, reflecting consistent demand from polymer and pharmaceutical intermediates sectors. Export volumes from China have expanded modestly over the past two years, while imports into the U.S. and EU have shown resilience despite broader chemical trade headwinds.
N-Phenylmaleimide is a white to off-white crystalline solid with a faint, characteristic odor; it has a melting point of approximately 89–91 °C and low volatility at ambient conditions. It is an aromatic heterocyclic compound classified as an imide and widely used as a reactive chemical intermediate. Its primary industrial application lies in copolymerization—particularly with styrenic and diene monomers—to enhance thermal stability, mechanical strength, and adhesion in specialty polymers and engineering resins. It is employed in the synthesis of high-performance materials for electronics encapsulants, aerospace composites, and photoresists, as well as in select pharmaceutical and agrochemical intermediates where controlled reactivity and aromatic functionality are required.
N-phenylmaleimide can be used as cross-linking agent in rubber vulcanization, can improve the heat resistance, impact resistance, hot melt processability. Also be used to produce heat-resistant polymers.
