Sodium hexametaphosphate is a kind of sodium phosphate polymer, which is transparent glass flake or white powder crystal. Strong hygroscopic, becomes sticky after hygroscopic, easy to be humid in the air, easy to dissolve in water, the solubility in water is large, but the dissolution rate is slow, and the aqueous solution is acidic. It is easy to hydrolyze into phosphite, and has the ability to generate soluble complexes for some metal ions (calcium, magnesium), so it can be used to soften water, and lead, silver, salt, etc., can also generate complexes.

white powder,density is 2.484(20 degree C),easily soluble in water,but not on organic solution,absorbent to dampness,and furn sticken when absorbed dampness in air.It's possible to form solvent compound with metallic ions such as Ca,Ba,Mg,Cu and Fe;It is a fine agent for water treatment.

For industrial use, such as oil field, paper-making, textile, dyeing, petrochemical industry, tanning industry, metallurgical industry and building material industry, it is mainly used as a water softening agent in solution for printing, dyeing, and boiler; Diffusant in papermaking; slow corrodent, floating agent, dispersing medium, high temperature agglomerant, detergent and soil analytical chemistry reagent. For food grade, it is mainly used as additive agent,pH adjusting agent and fermentation agent, and nourishment.

Sodium hexametaphosphate (SHMP) is widely used in paper production, textile, dyeing, petroleum, chemistry, metallurgy and construction materials etc., as water softener, flotation selecting agent, disperser and high temperature adhesive; In food industry it used as an additive, nourishing agent, quality improver, PH regulator, metal ions chelating agent, adhesive and leavening agent etc.
It is white powder, soluble in water but insoluble in organic solvent; It may form soluble chelates with ions of Ca, Ba, Mg, Cu, Fe etc. and is a good water treatment chemical.
In the food industry, sodium hexametaphosphate used as food quality improver, pH regulator, metal ions chelating agent, adhesive agent and expansive agent. Sodium hexametaphosphate for meat, fish intestinal and ham can improve holding water, increase knot and prevent fat oxidation; when for soy sauce it can prevent color, increase sticky, shorten fermentation period and regulation taste; it can improve out juice rate and viscosity, inhibit vitamin c decomposition when used in fruit beverage and cool beverage; this also improve expansion capacity, increases volume, enhance emulsion role and prevent cream body damage for ice cream; it prevent dairy products and beverage from gel precipitation; add it to beer can clarify wine, prevent pollution; as for beans, canned fruits and vegetables, it stabilize natural pigment and keep food color; it improves corrosion resistance when sprayed on the pickled meat.
Application in mineral processing and oil industry, sodium hexametaphosphate is a commonly used inhibitors of flotation. It mainly used to inhibit silica and silicate minerals, and carbonate minerals such as calcite, limestone. In addition, sodium hexametaphosphate also play the role of dispersant in flotation. In the nickel ore flotation process, after hauling mud cover on the surface of pentlandite, this is very negative to the flotation process. So, add a certain amount of this product is very favorable to pentlandite flotation recovery. Because the sodium hexametaphosphate makes flotation pulp disperse and reduce the surface covering of the serpentine in pentlandite.
In the oil industry, Sodium Hexametaphosphate is applied as a mud drilling additive which can avoid polyvalent metal ions precipitate, improve the ability of mud salt resistance and reduce mud water loss.
Sodium Hexametaphosphate applied to fiber industry can inhibit the generation of metal SOAP in the refining process; prevent the decomposition of hydrogen peroxide in the bleaching process; it can prevent color changes in dyeing; in paper making, the mix of sodium hexametaphosphate and sulfonation of benzene formaldehyde can be used to steel paper coating dispersant; etc.
