Sodium hexametaphosphate(SHMP) is a kind of sodium metaphosphate polymer, in the form of transparent glass flakes or white powdery crystals. It has strong hygroscopicity, becomes sticky after absorbing moisture, is easy to deliquesce in the air, and is easy to dissolve in water. The solubility is greater in water, but the dissolution rate is relatively warm. Its aqueous solution is acidic and easily hydrolyzed into phosphite.

Sodium hexametaphosphate(SHMP) has the ability to form soluble complexes for certain metal ions (calcium, magnesium). Therefore, it can be used to soften water, and can also form complexes with lead, silver, and barium salts.

Sodium hexametaphosphate is used as a flotation agent, refractory material, ceramics and other important additives in industrial water treatment, detergent additives, and mineral processing industries. Therefore, the quality of industrial grade sodium hexametaphosphate needs to be stable.

The large-scale production equipment of Chongqing Chuandong Chemical Group has also fully realized the basic work of combining para-formate and phosphate, and complementing thermal acid and wet acid. The main content of industrial grade sodium hexametaphosphate(SHMP) produced is 68%, and the quality is stable. The flow rate is good, and the dosage is small.
