Product Description
HDTMPA is an organophosphonic acid scale inhibitor supplied as a white crystalline powder. It is slightly soluble in water, with a solubility of less than 5% at room temperature.
HDTMPA can inhibit the formation of a wide range of mineral deposits, including calcium carbonate, calcium sulfate, barium sulfate, and iron oxide scales.
Among its various applications, HDTMPA is particularly effective for controlling calcium sulfate and barium sulfate scale. It provides strong scale inhibition performance and relatively long-lasting activity, making it especially suitable for oilfield squeeze treatment applications.
HDTMPA can also be used in boiler water treatment and other industrial water treatment systems where sulfate scale control is required.

Application Scenarios
1. Oilfield Water Treatment
HDTMPA is particularly suitable for oilfield scale control, especially in applications involving calcium sulfate and barium sulfate deposition.
Its strong and long-lasting scale inhibition performance makes it suitable for squeeze treatment, where a scale inhibitor is introduced into the formation to provide sustained protection against mineral deposition.
Typical applications include:
· Oilfield water injection systems
· Formation water treatment
· Downhole scale control
· Sulfate scale prevention
· Calcium sulfate scale control
· Barium sulfate scale control
· Oilfield squeeze treatment
2. Boiler Water Treatment
HDTMPA can be used in boiler water treatment formulations to help control mineral deposits and reduce the formation of hard-to-remove scale on heat-transfer surfaces.
3. Industrial Water Treatment
HDTMPA can be incorporated into industrial water treatment formulations where control of calcium sulfate, barium sulfate, calcium carbonate, and iron oxide deposits is required.
