Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium salt, frequently abbreviated as EDTMPS, is a phosphonate compound with chelating residences. It is usually utilized in various industrial processes, in particular in water treatment. Like different phosphonates, EDTMPS is effective in preventing scale formation and controlling corrosion in water structures.


Renowned for its chelating and inhibitory houses, it plays an essential role in water treatment by stopping scale formation and controlling corrosion in systems like cooling water and boilers. In the oil and gas area, EDTMPS is utilized for scale inhibition and corrosion manipulation in drilling and manufacturing systems, ensuring gold-standard performance in complex situations. The detergent industry incorporates it to decorate cleansing methods by sequestering metallic ions. Additionally, EDTMPS unearths use in the fabric enterprise for controlling metallic ions during dyeing processes, contributing to advanced coloration satisfaction. Its effectiveness extends to steel surface remedy, in which it inhibits corrosion and complements the sturdiness of metallic components.


With a commitment to satisfaction and performance, UniVOOK Chemical EDTMPS provides a modern-day chelating agent that is going past traditional standards.
