Sodium hexametaphosphate (SHMP) is a kind of sodium phosphate polymer, which is usually white powder crystal or transparent glass flake in appearance.
SHMP chemical has strong hygroscopic property and will become sticky after hygroscopic. It is very easy to
deliquescent in air and soluble in water with higher solubility and milder dissolution rate. Its aqueous solution is acid and easy
to hydrolyze to phosphite. In addition, it has ability to form a soluble complex for some metal ions, so it can be used to soft
water, as well as a wide range of uses in food processing and various industry fields.
