Industrial Grade Sodium Hexametaphosphate SHMP CAS 10124-56-8 for Water Treatment

Sodium Hexametaphosphate (SHMP, Graham's Salt, CAS:10124-56-8,EINECS:233-343-1, HS Code:2835391900, molecular formula (NaPO₃)₆, MW:611.77) is a white crystalline powder or glassy flake produced via high-temperature polymerization of sodium dihydrogen phosphate followed by rapid cooling and crushing. Our industrial grade SHMP features ≥68.0% P₂O₅ standard content, complying with HG/T 2519-2017 industrial standard. It exhibits excellent water solubility, strong hygroscopicity and outstanding chelating, dispersing and emulsifying properties, capable of forming stable soluble complexes with calcium, magnesium and heavy metal ions. As the most versatile polyphosphate industrial additive, it is widely used as water softener, scale inhibitor, dispersant and detergent builder across multiple industries.

Applications
Water Treatment Industry (Core Application)
Primary softener and scale inhibitor for industrial circulating cooling water, boiler water and reverse osmosis systems
Effectively chelates calcium and magnesium ions to prevent scale formation and equipment corrosion
Removes heavy metal ions from industrial wastewater through complexation
Detergent & Cleaning Industry
Key builder in laundry detergents and industrial cleaners, enhancing water softening and dirt removal efficiency
Prevents redeposition of soil on fabrics and improves detergent performance
Ceramic & Glass Industry
Dispersant for ceramic slurries, improving particle suspension and reducing viscosity
Fluxing agent in glass manufacturing to lower melting temperature and improve glass clarity
Other Industrial Applications
Textile dyeing auxiliary for leveling and anti-caking effects
Metal surface treatment agent for rust prevention and cleaning
Paper industry dispersant for pulp and coating formulations
