Product Description

Product Description

Hydroxyethylidene Diphosphonic Acid 

is a high-performance organophosphoruswith dual scale inhibition and corrosion inhibition properties.  Excellent chemical stability (effective at pH 2-12); Strong chelation of Ca, Mg, Fe to prevent scaling; Heat resistance (≤100°C), ideal for cooling/boiler water systems Eco-friendly, with better biodegradability than conventional phosphates. 

Applications

Industrial Water Treatment	Scale and corrosion inhibition in cooling water and boiler systems
Oilfield Chemicals	Scale inhibitor and corrosion inhibitor in water injection systems
Detergents	Chelating agent in phosphate-free/low-phosphate detergents
Textile & Dyeing	stabilizer and metal ion sequestrant
Paper Industry	Stabilizer in bleaching processes
Metal Cleaning	Corrosion inhibitor in acid pickling (e.g., HCl, H2SO4 systems)
