Properties:
1.HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.

2.HEDP shows excellent scale and corrosion inhibition effects under temperature 250℃.

3. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions.

4.Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt).

5. HEDP has good antiscale and visible threshold effects.

6.When built together with other water treatment chemicals, it shows good synergistic effects.

7.The solid state of HEDP is suitable for usage in winter and freezing districts.

8.The solid state of HEDP  can be used as cleaning agent in electronic fields and as additives in daily chemicals. 

Usage:
1.HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc..

2.In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent;

3. In non-cyanide electroplating, HEDP is used as chelating agent.
