HEDP CAS No.:2809-21-4
HEDP is used as a retardant in concrete, 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
Main Characteristic of HEDP:
1.an organo phosphoric acid corrosion inhibitor.
2.can dissolve the oxidized materials on these metals' surfaces.
3.Under 250℃ HEDP shows excellent scale and corrosion inhibition ability.
4. When built together with other water treatment chemicals, it shows good synergistic effects.
