[bis[6-[bis(phosphonomethyl)amino]hexyl]amino]methylphosphonic acid; Bis(Hexamethylene Triamine Penta (Methylene Phosphonic Acid))[BHMTPMPA]; Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)) BHMTPMP; Partially Neutralised Sodium Salt of Bis hexamethylene

1.Performance and usage
BHMTPMPA is a highly efficient chelating type scale inhibitor with good anti-scaling effect on carbonate scale and sulfate scale. BHMTPMPA has excellent water solubility and thermal stability in a wide pH range and high temperature of 120°C, and has high tolerance for calcium ions. It is used as a corrosion and scale inhibitor for oilfield water treatment, industrial circulating cooling water and boiler water treatment.
