Ethylene Diamine Tetra (Methylene Phosphonic Acid) Pentasodium Salt (EDTMP.Na5)

CAS. 7651-99-2

Application

The EDTMP.Na5 is water soluble, non-toxic and eco-friendly. It has good chemical stability and thermal resistance—even at 200 ℃, it maintains good performance. The sodium salt of EDTMP is especially suitable for inhibition of calcium sulfate and barium sulfate scale. It serves as scale and corrosion inhibitor in circulating water and boiler water systems, complexing agent in non-cyanide plating, water softener in dyeing industry, and cooling water treatment agent in power plant.
