STPP (Na5P3O10) were mostly used as one of the main auxiliaries for synthetic detergent; water softerner (mostly for the boiler); ceramic industry; tanning agent for leather making, auxiliary for dyeing; as an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud, etc; also it used as an oil contamination resistance agent in paper production.

Sodium Tripolyphosphate (STPP 94%) for Detergent Powder

As specification shows above, we could produce the required index product as clients needed. Mostly, the main content for Na5P3O10 , P2O5,Insoluble in water , Fe and PH value were stable. The differences in final usage are Bulk density and I Phase.


For our product, Bulk density between 0.5-0.75 were present granular looking, it always used on ceramic products. After smash, it becomes powder and density were between 0.7-0.95 and we call it 'high density' mostly. As Phase I, detergent industry always need lower index like 20-30 cause the lower Phase I were be better in thermostabilization and its Hydration speed of their final product.
