Large Quantity Supply Maleic Anhydride For Plastic Chemical Industry

As a key organic raw material derived from carboxylic acids, maleic anhydride is used in a wide range of fields, including fine chemicals, resin manufacturing, agriculture and pharmaceuticals, and water treatment. Its core advantage lies in its intramolecular double bond and anhydride groups—both active functional groups—which confer high reactivity in cross-linking reactions. Unsaturated polyester resins represent its largest downstream application, used in the curing and molding of fiberglass-reinforced plastics, engineered stone, and anti-corrosion coatings, resulting in products that are weather-resistant and corrosion-resistant. It is also used in the production of alkyd resins, water-based coatings, and ink resins to enhance paint film adhesion and drying speed. In the agrochemical sector, they are used to synthesize maleic hydrazide, insecticides, and herbicide intermediates to regulate crop growth; in the pharmaceutical sector, they are used to prepare maleic acid salt active pharmaceutical ingredients (APIs) and drug intermediates to improve drug water solubility. In the water treatment industry, they are used to synthesize organic polymer flocculants and scale and corrosion inhibitors to stabilize water quality systems. Additionally, it can be used to produce plasticizers, paper sizing agents, and waterproof finishing additives for textiles, as well as serving as chemical analysis reagents, rubber vulcanization aids, and lubricant additives. With its versatility, it is well-suited for large-scale, continuous industrial production and boasts high raw material conversion rates. As a globally essential bulk organic intermediate with a broad range of downstream applications, it meets the bulk procurement needs of multiple industries.

The product strictly complies with the GB/T 2961-2014 national standard, accompanied by a complete set of MSDS, commodity inspection reports, and hazardous packaging certificates, and meets EU REACH import and export requirements. Standard packaging includes 200 kg galvanized closed-top steel drums and 1,000 L IBC containers. For large volumes, bulk transport via tank containers is available. Storing and transporting the product in a sealed, light-protected environment effectively delays oxidation and discoloration. Supply is stable and ample, supporting full-container and consolidated shipments for international trade, and meeting global chemical procurement and custom fine chemical production needs.
