In the vast landscape of industrial chemicals, Maleic Anhydride (MAH) stands out for its exceptional versatility and reactivity. This organic compound, represented by the formula C4H2O3, is a white crystalline solid with a characteristic pungent odor. Its ability to readily react with water to form maleic acid, and its role as a key intermediate in numerous synthesis pathways, makes it indispensable across a wide array of industries. NINGBO INNO PHARMCHEM CO.,LTD. is proud to be a supplier of this vital chemical.

The industrial production of Maleic Anhydride is primarily achieved through the vapor-phase oxidation of n-butane, a process that has largely replaced older methods using benzene due to economic and environmental considerations. This efficient maleic anhydride production process ensures a stable and high-quality supply chain for its many applications. The inherent maleic anhydride chemical properties, including its unsaturated cyclic anhydride structure, grant it a broad reaction spectrum.

Perhaps the most significant application of Maleic Anhydride is in the production of unsaturated polyester resins (UPRs). These resins are critical components in the manufacturing of fiberglass-reinforced plastics, widely used in the automotive, construction, and marine sectors for their strength, durability, and corrosion resistance. The maleic anhydride uses in plastics are extensive, often improving impact resistance and compatibility when incorporated into polymer matrices.

Beyond resins, Maleic Anhydride is a foundational chemical for several other industries. In the coatings sector, it enhances the performance of paints and varnishes. For pharmaceuticals and agrochemicals, it serves as a crucial building block for synthesizing active ingredients and functional compounds. The maleic anhydride applications in pharmaceuticals are particularly noteworthy, contributing to the development of novel therapeutics. Furthermore, it finds use in water treatment chemicals as a scale and corrosion inhibitor, and in the production of various surfactants essential for detergents and industrial cleaning.

The global demand for Maleic Anhydride underscores its importance as a chemical intermediate. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing the market with premium Maleic Anhydride, supporting innovation and manufacturing excellence across industries.
