Maleic Anhydride as a Core Resin Monomer

Maleic anhydride (MA) is one of the most important industrial organic chemicals, consumed primarily in unsaturated polyester resins used in fibreglass composites for marine, construction, and automotive applications. It reacts readily with polyols and diacids to produce the ester backbone, and its double bond provides the crosslinking site for styrene polymerisation. MA is also used to produce succinic anhydride, malic acid, and a range of maleate/fumarate co-monomers.

Supply and Packaging

Maleic anhydride is hygroscopic and reactive with moisture. Terracore supplies in sealed, moisture-barrier bags (25 kg) and prill/briquette form. ISO container supply is available for large volumes. Reactive chemical handling protocols and full SDS/COA documentation are provided.

Applications

Unsaturated polyester resin (UPR) monomer
Alkyd resin modification
Maleic acid and fumaric acid hydration
Agricultural chemical and herbicide production
Lubricant additive and ashless dispersant
Paper sizing and textile auxiliaries
