Sodium Hexametaphosphate(SHMP), the white powder in appearance, is easily soluble in water but insoluble in organic solvents. It has strong hygroscopicity and can absorb humidity from the air, causing the product to turn pasty in form. More importantly, it is used in these industries, and they are soap, detergents, water treatment, metal finishing and plating, pulp and paper manufacture, synthesis of polymers, photographic products, textiles, scale removal, and agriculture, etc.
