Polyepoxysuccinic acid

Polyepoxysuccinic acid (CAS 51274-37-4 ), also marketed as PESA, is a biodegradable polymeric chelating agent used in industrial water and process systems. It controls scale deposition and inhibits corrosion by sequestering hardness ions. This chemical effectively manages calcium, magnesium, and barium before they precipitate on equipment surfaces. In cooling water and boiler systems, PESA prevents calcium carbonate and calcium sulfate scale from forming on heat transfer surfaces. By maintaining thermal efficiency and reducing downtime, it serves as a critical component in industrial maintenance. Oil and gas operators use it in produced water treatment and injection water conditioning for flow assurance. Mineral scale in pipelines and wellbores causes significant problems that this agent helps mitigate. Desalination and reverse osmosis plants apply it as an antiscalant to extend membrane service life significantly. It keeps sparingly soluble salts in solution to prevent fouling. Its environmental profile makes it a preferred substitute for phosphonate-based scale inhibitors in regions with strict phosphorus discharge limits. Polyepoxysuccinic acid is supplied as an aqueous solution, typically at 40% active content. It is available in technical grade for industrial water treatment applications across various sectors. Bulk supply is standard in IBC totes and drummed quantities for large-scale operations. Documentation typically includes COA, MSDS, and biodegradability test data to support regulatory compliance in sensitive environments. Contact us for supply of Polyepoxysuccinic acid Request Quote
