It is a surfactant, and has got outstanding emulsification to lubricants and fat. It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. This product has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.ITEMSPECIFICATIONAppearanceWhiteGranularorPowderNa5P3O1095%Min.P2O557.0%Min.WaterInsoluble0.05%MaxpHValue9.5-10.0Fluoride10mg/KGMax.As1mg/KGMax.Lead1mg/KGMax.Cd1mg/KGMax.Hg1mg/KGMax.Al200mg/KGMax.Heavymetals(AsPb)10mg/KGMax.BulkDensity0.70g/ml-0.80g/mlWhiteness85%MinClBytesting%SO4Bytesting%LossonIgnition(105ºC,1hour)0.5%Max.Through80mesh25%MinThrough100mesh45%MinUses ofSodium Tripolyphosphate STPP 95%In foodstuff industry, it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans.
