Product Features
HexaMethyleneDiamineTetra (MethylenePhosphonic Acid) (HMDTMPA) is a white crystalline powder at room temperature, slightly soluble in water with a solubility of less than 5%.
It can inhibit most scale formations such as calcium carbonate, calcium sulfate, barium sulfate, and ferric oxide.
Technical Specification
Appearance: White crystalline powder
Active component (as HDTPMA-), %: Min 97.0
chloride (Cl-), %: Max 0.5

Applications & Usage
As a water treatment chemical, HMDTMPA is used as a scale inhibitor for calcium sulfate and barium sulfate, particularly for calcium sulfate. It has a high scale inhibition rate and can be effective for a long duration.
HexaMethyleneDiamineTetra (MethylenePhosphonic Acid) can be used for fracturing treatment in oilfields and for water treatment in boilers.
