Maleic acid copolymer

Maleic acid copolymer (CAS 113221-69-5) is a synthetic polymer used as a scale inhibitor, dispersant, and chelating agent.

Where is Maleic acid copolymer used?

• Industrial water treatment: inhibits calcium carbonate, calcium sulfate, and calcium phosphate scale in cooling towers, boilers, and reverse osmosis systems
• Detergent and hard-surface cleaners: sequesters hardness ions
• Textile processing: prevents metal ion interference and improves bath stability during dyeing and finishing
• Paper manufacturing: controls pitch and deposit buildup on process equipment
• It keeps soils suspended and improves rinse performance in consumer and institutional products.

Good to know: Specifications vary by molecular weight and active content depending on the target application. Buyers should confirm active solids content and pH range with suppliers when evaluating grades for specific formulation or dosing requirements.
