Import 1-Hydroxy Ethylidene-1 — Buy in Bulk from Supplier in China

Shandong Taihe Water Treatment Co., Ltd. supplies 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), CAS No. 2809-21-4, from its base in Zaozhuang, Shandong, China. This organophosphoric acid functions as a corrosion inhibitor and scale inhibitor in industrial water systems. It chelates with Fe, Cu, and Zn ions, dissolving oxidised materials on metal surfaces. HEDP maintains chemical stability at high pH, resists hydrolysis, and tolerates acid, alkali, and chlorine oxidation better than many other organophosphoric acids. It forms a stable six-element chelating complex, particularly with calcium ions, providing visible threshold effects.

The product is offered in two physical forms: a colourless to light yellow transparent liquid (58-62% active content) and a white crystal powder (89% minimum active content). The powder form is suited for use in winter and freezing regions. Typical applications include scale and corrosion control in circulating cooling water, oil fields, and low-pressure boilers across the power, chemical, metallurgy, and fertiliser sectors. It also serves as a metal and non-metal detergent in light weaving, a peroxide stabiliser and dye-fixing agent in dyeing, and a chelating agent in non-cyanide electroplating. Dosage ranges from 1-10 mg/L as a scale inhibitor, 10-50 mg/L as a corrosion inhibitor, and 1000-2000 mg/L as a detergent. It is often used in combination with polycarboxylic acids for synergistic performance.

Shandong Taihe Water Treatment Co., Ltd. is located in the Hongcun area of Xiwangzhuang Town, Shizhong District, Zaozhuang, Shandong Province, China. The supplier is listed on the platform as an imported-tier entity.
