Tetrasodium salt of Amino Trimethylene Phosphonic Acid or ATMP Na5

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

ATMP chemical has better antiscale performance than that of polyphosphate through its excellent chelating ability, low threshold inhibition and lattice distortion process. It can prevent scale formation in water systems. ATMP is the phosphonate analog of nitrilotriacetic acid. ATMP is a highly effective chelating agent and sequestering agent.

  • ATMP Na5 prevents scale formation, calcium carbonate in particular, in water system
  • ATMP Na5 is of high purity, and thus can be used in woven & dyeing industries and as metal surface treatment agent.
  • ATMP Na5 decreases scale formation and inhibits corrosion of metal equipment and pipeline
  • ATMP Na5 is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant.
  • ATMP Na5 is suitable for usage in winter and freezing districts.
  • Multifunctional and cost effective performance makes it an excellentreplacement to other sequestrants e.g EDTA, DTPA, NTA, Metaclaw, Trilon, Versene, Dissolvine, Dequest, Codex, Sequacel, Acinol etc.
