Pentasodium aminotrimethylene phosphonate

Pentasodium aminotrimethylene phosphonate (CAS 2235-43-0) is the pentasodium salt form of ATMP, a phosphonate chelating agent used to control scale formation and metal ion interference.

Where is Pentasodium aminotrimethylene phosphonate used?

• Water treatment and process fluids: sequesters calcium, magnesium and heavy metal ions
• Cooling water and boiler systems: inhibits calcium carbonate and calcium sulfate scale deposition, protecting heat exchange surfaces
• Textile and paper processing: sequesters hardness ions in process water, preventing interference with dyes, bleaches and sizing agents
• Oilfield: scale inhibitor in injection water and produced water treatment
• Mining and metals processing: stabilizes metal ion concentrations in leaching circuits and metal surface treatment baths
• It inhibits mineral scaling in pipelines and wellbores.

Commercial specifications
