entasodiumSalt Of Ethylene Diamine Tetra(Methylene Phosponic Acid) (EDTMP.Na5) [CAS] 7651-99-2      Molecular Weight: 546.13 1,Properties EDTMP Na5 is a neutral product, EDTMP Na5 is a multi-nitrogen-containing organic phosphates, a cathodic type inhibitor. It is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200°C. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMP.Na5 shows better antiscale effects to calcium sulfate and barium.EDTMP · Na5 is used for circulating water and boiler water scale and corrosion inhibitor, non-cyanide electroplating of complexing agent, softening agent in dyeing industry, power plant cooling Water Treatment. Solid products of EDTMP.Na5 have slightly moisture absorption , are convenient for transportation and using in cold conditions. 2,Specification:
