Sodium tripolyphosphate(STPP)is a kind of inorganic surfactant with certain properties oforganic surfactant.

　　CD provide industrial grade STPP, ceramic STPP and food grade STPP.

　　Industrial Grade STPP

　　STPP is white granular or powder with a density of 0.35-0.95g/cm3and a melting point of 622°C.It is soluble in water and alkaline in aqueous solution. Hydrolysis into orthophosphategradually in water, which has good ability to complex metal ions. It can complex with Ca, Mg, Feand other metal ions to form soluble complexes. It can soften hard water. As an inorganicsurfactant, it has some properties of organic surfactant. The industrial grade STPP of HuishuiCD is made of authentic raw materials by thermal process, with less impurities, low heavy metalcontent and the highest cost performance ratio. It can be used as additives for syntheticdetergents, water softeners for industrial use, water softeners for boilers, drilling muddispersants, paper industry as antifouling agents, soap synergists and strip soap oilprecipitation and frosting prevention, etc.

　　Ceramic STPP

　　Ceramic STPP of CD are mainly used in ceramic industry as ceramic degumming agent, waterreducing agent, synthetic detergent additives, industrial water softener, boiler water softener,drilling mud dispersant, paper industry as anti-oil stain agent, soap synergist and Anti-stripsoap oil precipitation and frosting. It has strong emulsifying effect on lubricating oil andfat. It can be used to adjust the PH value of buffer soap solution and as dispersant whensuspension is prepared in industries such as dyeing additives, paint, kaolin, magnesium oxideand calcium carbonate.

　　Food Grade STPP

　　The food grade STPPof CD is mainly used as a quality improver in meat products, canned meat andother food industries. Food-grade STPP produced by CD possesses food production license. It usesauthentic thermal process phosphoric acid and soda ash with stable quality and low content ofheavy metals.
