Maleic Anhydride (MA), known by its CAS number 108-31-6, is a fundamental organic intermediate that plays a pivotal role in the production of a wide array of resins, most notably unsaturated polyester resins (UPR) and alkyd resins. As a prominent manufacturer and supplier in China, we are dedicated to providing formulators with high-purity Maleic Anhydride, ensuring the quality and performance of their final resin products. For businesses looking to buy Maleic Anhydride, understanding its applications in resin manufacturing is key to appreciating its value.

The versatility of Maleic Anhydride in resin synthesis is remarkable. In the creation of unsaturated polyester resins, MA is reacted with glycols to form polyester chains that are then cross-linked with reactive monomers, typically styrene. These UPRs are the backbone of many composite materials used in construction, marine applications, automotive components, and consumer goods due to their excellent mechanical strength, chemical resistance, and processability. A consistent supply of high-quality Maleic Anhydride from a reliable manufacturer is essential for achieving the desired properties in these demanding applications.

Similarly, Maleic Anhydride is integral to the production of alkyd resins, which are widely employed in solvent-based coatings, paints, and varnishes. The incorporation of MA into the alkyd backbone modifies the resin's properties, influencing drying time, hardness, adhesion, and overall durability. This makes it an indispensable ingredient for manufacturers of architectural paints, industrial finishes, and automotive primers. Sourcing from a trusted Maleic Anhydride supplier like us ensures that your alkyd resin formulations will meet stringent performance requirements.

The chemical industry relies heavily on efficient and cost-effective production methods for key intermediates. Maleic Anhydride is typically manufactured through the vapor-phase oxidation of n-butane or benzene, a process that requires precise catalytic control to achieve high yields and purity. As a leading manufacturer, we leverage advanced production techniques to deliver Maleic Anhydride with a minimum purity of 99.5%, ensuring it meets the exacting standards of resin producers. Purchasing directly from us offers a direct route to quality and competitive pricing.
