HEDP 98%
SINOBIO
2931900090
-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP) 98% is a high-performance organophosphonic acid corrosion and scale inhibitor manufactured by SINOBIO, a leading supplier of water treatment chemicals. With CAS No. 2809-21-4, molecular formula C₂H₈O₇P₂, and molecular weight 206.02, this product is engineered to deliver exceptional performance in industrial water treatment and related applications.
As a core water treatment chemical, HEDP 98% stands out for its ability to chelate with metal ions (Fe, Cu, Zn) to form stable complexes, dissolve oxide layers on metal surfaces, and maintain efficiency even under extreme conditions. It is widely recognized for its versatility, making it a preferred choice in sectors ranging from power generation to pharmaceuticals.
HEDP 98% retains its scale and corrosion inhibition effectiveness at temperatures up to 250°C, outperforming many conventional water treatment chemicals in high-heat environments such as industrial boilers and oilfield systems.
This product exhibits excellent chemical stability under high pH conditions, resisting hydrolysis and decomposition from light, heat, or oxidizing agents (e.g., chlorine). Its tolerance to acids, alkalis, and oxidation is superior to other organophosphonic acids, ensuring long-lasting performance in diverse water systems.
HEDP 98% forms hexavalent chelating complexes with metal ions in water, particularly calcium ions, delivering strong antiscale effects and a notable threshold effect. When blended with other water treatment chemicals (e.g., polycarboxylates), it enhances overall efficiency through synergistic interactions.
In its solid form, HEDP 98% is a high-purity white crystalline powder, ideal for cold climates. Its purity also makes it suitable for sensitive applications like electronics cleaning and as an additive in daily chemicals.
Item | Standard |
Appearance | White crystalline powder |
Active content (as HEDP·H₂O) | 98.0% min |
Phosphorous acid (as PO₃³⁻) | 0.8% max |
Phosphoric acid (as PO₄³⁻) | 0.5% max |
Chloride (as Cl⁻) | 100 ppm max |
pH (1% solution @20°C) | 2.0 max |
Iron content (Fe) | 20.0 ppm max |
HEDP 98% is widely used as a scale and corrosion inhibitor in circulating cooling water systems, low-pressure boilers, and oilfield operations across power, chemical, metallurgy, and fertilizer industries. Its chelating action prevents scale buildup, reducing maintenance costs and improving system efficiency.
In the light textile industry, HEDP 98% serves as an effective cleaning agent. It dissolves metal ions without aggressive damage to substrates, ensures easy passivation after pickling, and minimizes rust formation—critical for maintaining material integrity.
As a peroxide stabilizer and dye-fixing agent in the dyeing industry, HEDP 98% enhances color retention and prevents peroxide degradation, ensuring consistent results in textile processing.
It acts as a reliable chelating agent in cyanide-free electroplating, improving coating adhesion and uniformity while supporting eco-friendly plating practices.
HEDP 98% functions as a carrier for radioactive elements in pharmaceutical applications, leveraging its stability and chelation properties for controlled delivery.
Packaging: Available in 25kg bags, with bulk options of 25 MT (with pallet) or 27 MT (without pallet).
Storage: Store in a cool, dry, and shaded area. Shelf life is 1 year under proper storage conditions.
HEDP 98% (CAS 2809-21-4) by SINOBIO combines high performance, versatility, and reliability, making it the ideal solution for demanding water treatment and industrial applications. Contact us today to learn more about bulk pricing or technical support.
