Ethylene Diamine Tetra (Methylene Phosphonic Acid) Pentasodium Salt (for water treatment)

Technical Data Sheet

EDTMP·Na5 is a neutral product. EDTMP·Na5 is a nitrogen-containing organic polyphosphonate, which is a cathodic corrosion inhibitor. It is miscible with water, non-toxic and non-polluting, with good chemical stability and temperature resistance, and still has a good scale inhibition effect at 200°C. It can dissociate into 8 positive and negative ions in aqueous solution, so it can chelate with multiple metal ions to form multiple monomer structure macromolecular network complexes, which are loosely dispersed in water, destroying the normal crystallization of calcium scale. EDTMP sodium salt has a good scale inhibition effect on calcium sulfate and barium sulfate scale.

Scale inhibitor, complexing agent for cyanide-free electroplating, water softener for printing and dyeing industry, cooling water treatment for power plants, etc.

The solid product of EDTMP·Na5 has slight hygroscopicity, which is convenient for transportation and use in cold conditions.

Packaging and storage
EDTMPA is packaged in composite plastic woven bags or packaging that meets export environmental protection requirements. Each bag has a net weight of 25kg and is stored in a cool place indoors. The storage period is ten months.

Safety protection
EDTMPA is an acidic solid. Pay attention to labor protection during operation and avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
