Sodium Hexametaphosphate (SHMP)

Product Overview

Sodium Hexametaphosphate (SHMP) is a white, crystalline, or granular inorganic phosphate compound with the molecular formula Na₆P₆O₁₈. It is highly soluble in water and known for its chelating, dispersing, and water-softening properties, making it a versatile additive in food, water treatment, detergents, ceramics, and chemical industries.

SHMP is widely used as a sequestrant, stabilizer, and deflocculant, providing excellent performance in industrial and commercial applications.

Manufacturing & Quality Control

Sodium Hexametaphosphate is produced by heating a mixture of monosodium phosphate and disodium phosphate, followed by controlled cooling and crystallization. Quality control ensures:

• High purity and low heavy metal content

• Consistent particle size and solubility

• Compliance with industrial, food, and chemical standards

Each batch undergoes assay, solubility, and moisture content testing to meet customer specifications.
