Sodium Tripolyphosphate-STPP

Introduction for Sodium Tripolyphosphate

(STPP, 94% Tech)

Sodium Tripolyphosphate belongs to inorganic salt chemicals as picture shows below, it looks as white powder(right) or granular (left)

Application:

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.

Specification:

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.

Package:

We support package in 25kg/50kg/1000kg net WPP/PE bags
