Product Description

Product Overview:

Maleic Anhydride (MA) is a highly reactive organic compound with excellent chemical properties, making it an essential raw material for various industrial applications. Our MA is produced through advanced oxidation processes, ensuring superior purity (≥99.5%) and consistent quality. It appears as white crystalline flakes or powder with low moisture content, guaranteeing stability during storage and transportation.

This versatile chemical serves as a key intermediate in producing unsaturated polyester resins (UPR), coatings, plasticizers, and agricultural chemicals. Its unique molecular structure enables it to enhance product performance by improving hardness, durability, and chemical resistance in end applications. The industrial-grade MA is particularly valued for its role in manufacturing high-quality composite materials, while the high-purity grade meets stringent requirements for pharmaceutical and specialty chemical production.

Our MA is manufactured under strict quality control measures in ISO-certified facilities, with each batch tested to ensure compliance with international standards. The product's excellent solubility and reactivity make it ideal for both large-scale industrial processes and specialized chemical synthesis. We offer flexible packaging solutions and reliable global supply to meet diverse customer needs.

With low toxicity and well-documented handling procedures, our Maleic Anhydride combines performance with safety, making it the preferred choice for manufacturers worldwide seeking a dependable and high-quality chemical raw material.

Primary Applications:

• Resins & Polymers: Key raw material for unsaturated polyester resins (UPR) and alkyd resins, enhancing durability and performance in composite materials.

• Coatings & Adhesives: Improves adhesion, hardness, and chemical resistance in industrial coatings and adhesives.

• Agriculture: Intermediate for manufacturing pesticides, herbicides, and plant growth regulators.

• Pharmaceuticals: Used in the synthesis of active pharmaceutical ingredients (APIs) and other intermediates.

• Plasticizers: Essential for producing high-performance plasticizers used in PVC and other polymers.
