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.
Procurement resource
Plan your maleic anhydride enquiry
The product specification above is a starting point for supplier evaluation. Confirm the agreed specification, supplied form, documentation and application requirements before placing an order.
01 · Technical documents
Request the current technical data sheet (TDS), safety data sheet (SDS / MSDS) and a relevant certificate of analysis (COA). A TDS describes the product, an SDS supports hazard review, and a COA records results for an identified batch. They are not interchangeable.
02 · Application review
Share the intended use, such as unsaturated polyester resin or another industrial intermediate application, with your technical team. A purity figure alone does not establish suitability. Agree the acceptance criteria, test methods and any destination-specific documentation requirements.
03 · Packaging and quotation
Specify solid or molten material, requested quantity, preferred packaging, destination port and target shipment window. Packaging suitability, availability, lead time and commercial terms must be confirmed in the quotation; this page is not a stock or delivery guarantee.
Questions buyers often ask
Is the listed 99.5% purity a substitute for a batch COA?
No. Compare the agreed purchase specification with a COA identifying the relevant batch and test methods. Ask for clarification if a document is a sample rather than a record for the offered batch.
What should I include when requesting maleic anhydride pricing?
Include the product and supplied form, quantity, destination, packaging preference, timing and required documents. These details help the sales team prepare a relevant response without assuming price, stock or freight availability.
