    Product Overview

    Sodium hexametaphosphate SHMP also known as sodium polyphosphates, is an inorganic compound composed of six phosphate anions and eighteen sodium cations. Sodium hexametaphosphate chemical formula (NaPO3)6 appears as a white crystalline powder that is soluble in water, forming alkaline solutions, with sodium hexametaphosphate pH ranging from 9 to 11 depending on the concentration. It has applications in meat processing, detergent making, metal cleaners, coatings, and ceramics. Sodium hexametaphosphate in water treatment is used to sequester calcium and prevent scaling.
