Maleic acid copolymer

Maleic acid copolymer (CAS 113221-69-5) is a synthetic polymer used across water treatment and industrial cleaning as a scale inhibitor, dispersant, and chelating agent. It prevents mineral deposits and controls particle dispersion in process water and formulated cleaning products.

In industrial water treatment, it inhibits calcium carbonate, calcium sulfate, and calcium phosphate scale formation in cooling towers, boilers, and reverse osmosis systems. Detergent and hard-surface cleaner formulations use it to sequester hardness ions.

By keeping soils suspended, it improves rinse performance in both consumer and institutional products. Textile processing operations apply it during dyeing and finishing to prevent metal ion interference and improve bath stability.

In paper manufacturing, it controls pitch and deposit buildup on process equipment, reducing downtime and improving runnability. This versatile polymer ensures efficiency across various high-demand industrial environments.

Maleic acid copolymer is supplied as an aqueous solution, typically at concentrations suited to direct dosing in water treatment and cleaning applications. Technical grade is the standard commercial offering for most buyers.

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.
