Information
Sodium Hexametaphosphate (SHMP), the white crystalline powder in appearance, is an inorganic substance with the molecular formula (NaPO3)6. It is very soluble in water but insoluble in organic solvents. It is highly hygroscopic, and it can gradually absorb moisture when exposed to the air and become a viscous gel. Of course, the most important thing is that SHMP has a wide range of applications in the industrial and food fields. For example, SHMP chemical can be used for soap, detergents, water treatment, metal finishing and plating, pulp and paper manufacture, synthesis of polymers, photographic products, textiles, scale removal and food additives, etc.
