Molecular Formula: C3H8NO9P3Na4 Molecular Weight: 387
ATMP•Na4 is the neutral sodium salt of ATMP, it can inhibit the scale formation, especially calcium carbonate, in water system. ATMP•Na4 is suitable for circulating cool system in power plant, oil refinery plant. ATMP•Na4 is also used as scale inhibitor in oilfield refill water system and reverse osmosis membrane. ATMP•Na4 has good compatibility with other additives, particularly suitable for neutral to acidic formulations, without ammonia flavor.
