Hydroxyethylidene-1,1-diphosphonic Acid (HEDP), also known as Etidronic Acid, is a phosphonate that stands out due to its remarkable chemical stability and synergistic capabilities. At NINGBO INNO PHARMCHEM CO.,LTD., we emphasize these crucial properties that make HEDP a preferred choice for many industrial applications, especially in water treatment.

HEDP exhibits excellent chemical stability across a wide operational spectrum. It maintains its efficacy under high pH conditions, resisting hydrolysis and decomposition that can occur with other chemicals when exposed to ordinary light and heat. This inherent stability ensures that HEDP provides consistent performance, even in challenging environments where other compounds might degrade.

A key advantage of HEDP is its remarkable tolerance to acid, alkali, and chlorine oxidation. This makes it a robust option compared to other organophosphoric acids, as it can withstand a broader range of chemical conditions without losing its functional properties. This attribute is particularly valuable in complex industrial water systems where various chemicals might be present.

Furthermore, HEDP demonstrates potent synergistic effects when combined with other water treatment chemicals. For instance, when used alongside polycarboxylic acids, it significantly enhances the overall scale and corrosion inhibition performance. This synergistic interaction allows for lower overall chemical dosages while achieving superior results, leading to cost efficiencies and reduced environmental impact.

The ability of HEDP to form stable complexes, especially with calcium ions, is central to its effectiveness as a scale inhibitor. This property, combined with its synergistic potential, makes it a cornerstone in advanced water treatment formulations. NINGBO INNO PHARMCHEM CO.,LTD. is committed to leveraging these chemical characteristics to provide our clients with optimized solutions that deliver superior performance and reliability.
