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.
SHMP sodium hexametaphosphate is widely used, especially in the industrial and food fields. For example, SHMP chemical can be used for water treatment, soap, detergents, metal finishing and plating, pulp and paper manufacture, synthesis of polymers, photographic products, textiles, scale removal and food additives, etc.

Main Uses of Sodium Hexametaphosphate (SHMP) 68%
- Industrial Grade SHMP Hexametaphosphate. SHMP is widely used in oil field, paper-making, textile, printing and dyeing, petrochemical, tanning, boiler, metallurgical industry and building material industries, so it can be used as water softener, buffering agents, flotation agent and high temperature binding agent.
- Food Grade SHMP. Sodium hexametaphosphate in food can be used as additive agent, nutrients, quality improver, PH value adjustment agent, metal ion chelating agents, binders, extenders,etc.
Performance Characteristics
- Water Softening and Scale Inhibition. This chemical combines with calcium and magnesium ions in water to form soluble complexes, thereby reducing water hardness and preventing scale formation. It can also be used as a cleaning agent and descaling agent for cleaning scale and dirt from pipes, equipment, and other surfaces.
- Dispersion and Suspension. SHMP has diffusion and deflocculation properties, effectively preventing the crystallization of calcium, magnesium, and iron salts in solution. It keeps suspended particles dispersed, preventing particle aggregation and precipitation.
- Corrosion Inhibition. Sodium hexametaphosphate forms a protective film on metal surfaces, inhibiting corrosion and preventing it. It is commonly used in metal surface treatment and circulating cooling water systems.
- Food Improvement. In the food industry, sodium hexametaphosphate can be used as a quality improver, pH adjuster, metal ion chelator, adhesive, and bulking agent. It can improve the water retention and binding properties of meat products, prevent fat oxidation, increase the juice yield and viscosity of fruit beverages, and inhibit the decomposition of vitamin C.
