  • AVA Chemicals is a leading DTPMP producer, DTPMP supplier, DTPMP manufacturer.
  • AVA Chemicals est un producteur DTPMP fournisseur leader DTPMP, fabricant DTPMP.

DTPMP chemical is normally delivered as salts, because the acid form has very limited solubility in water and tends to crystallize in concentrated aqueous solutions. DTPMP is a nitrogenous organic polyphosphonic acid. DTPMP shows very good inhibition of the precipitation of barium sulfate (BaSO4). At high alkali and high temperature (above 210 oC) environments DTPMP has better scale and corrosion inhibition effect than other phosphonates. DPTMP is a highly effective chelating agent and sequestering agent.
