Industrial Grade Phosphonate Salts HEDP Organophosphonic Acid-based

HEDP

CAS No. 2809-21-4

Performance and Application

An organic phosphonic acid scale/corrosion inhibitor. Chelates metal ions (Fe, Cu, Zn), dissolves metal oxides. Effective up to 250°C, stable at high pH, resistant to hydrolysis and decomposition. Good chemical/chlorine resistance compared to other phosphonates. Forms stable chelates with Ca²+, providing scale inhibition and a threshold effect. Synergistic with other water treatment agents.

(1).Solid is high-purity, suitable for cold climates; also for electronics cleaning and daily chemicals.

(2).Used for scale/corrosion inhibition in cooling water, low/medium pressure boilers, oilfield water injection, and pipelines. Also used in textiles as a cleaner
