Maleic Anhydride Market Analysis:
According to IMARC Group's latest research on the global maleic anhydride market, the maleic anhydride market was valued at USD 3.68 Billion in 2025 and is projected to reach USD 5.26 Billion by 2034, exhibiting a CAGR of 3.93%, with the industry witnessing steady expansion driven by rising demand for unsaturated polyester resin in construction and marine composites, surging use of 1,4-butanediol in engineering plastics, and steady feedstock optimization toward n-butane. Asia Pacific currently dominates the market, holding a share of over 45%, anchored by large-scale integrated chemical complexes across China and India.
Maleic anhydride is an organic chemical intermediate produced through the catalytic oxidation of n-butane or benzene, used primarily in the manufacture of unsaturated polyester resin, 1,4-butanediol, lubricant additives, and specialty copolymers. The compound serves as a versatile building block across construction, automotive, marine, textile, and industrial coating applications, with the industry evolving from a largely benzene-based commodity chemical business into a feedstock-optimized, application-diversified sector.
