  Dear Sir,
  we have been a professional supplier in water treatment chemicals in China for many years, in the following we list currently our popular exporting products as follows:
  
  1-Hydroxy Ethylidene-1,1-Diphosphonic Acid(HEDP)
  CAS No.:2809-21-4
  Molecular Formula: C2H8O7P2
  Molecular Weight:206.02
  Production:500MT/month
  Main specification:liquid 60 % and powder 90%
  
  1)HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.It can dissolve the oxidized materials on these metals’ surfaces.
  2)HEDP shows excellent scale and corrosion inhibition effects under temperature 250oC.
  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. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt).
  4)?HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore.
  5)HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects。The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.?
