Ethylene Diamine Tetra Methylene Phosphonic Acid Sodium (EDTMPS)

Properties: EDTMPS is brown yellow transparent liquid. It has good chemical stability and has excellent scale inhibition effect for calcium carbonate and calcium sulfate under 200 degrees. At the same time, it has good dispersion and corrosion inhibition performance.

Usage: As the scale inhibitor in circulation chilled water and boiler water and is also used as a complexing agent or water softener in other industrial water.
