Maleic Anhydride is a versatile chemical intermediate widely used in:
- Unsaturated Polyester Resin (UPR): The largest end-use of MA, serving as a key raw material for FRP (Fiber Reinforced Plastic), gel coats, and high-performance coatings, widely used in wind power, automotive, marine, and construction industries.
- Paints & Adhesives: A critical component in the production of alkyd resins, which enhance the adhesion, weather resistance, and anti-corrosion properties of paints, coatings, and industrial adhesives.
- Chemical Intermediates: A fundamental building block for manufacturing high-value derivatives, including fumaric acid, succinic acid, tetrahydrofuran (THF), and various pharmaceutical and agrochemical intermediates.
- Artificial Stone & Composite Materials: Used in the production of engineered stone, quartz stone, and architectural decoration materials, improving product strength, durability, and chemical resistance.
- Water Treatment Chemicals: Applied in the formulation of oxygen scavengers and corrosion inhibitors for oilfield operations and industrial circulating water systems, effectively preventing pipeline corrosion and scaling.
