Sodium Tri poly Phosphate
EXCLUSIVE FEATURES
a white powder with no distinguishing odour Easily soluble in water;
It has different bulk density, i.e. low density 0.35-0.5g/cm 3 , medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm 3 .
This product has two crystalline forms, namely phase I (high temperature phase) and
phase II (low temperature phase).
The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .
APPLICATIONS
Synthetic detergent, synergist for soap
Ceramic tiles
Water treatment
Metal treatment
Paints
Leather tanning
Flame retardant
Water softener
As an effective dispersion agent or suspensions of coatings, kaolin, magnesium oxide,
calcium carbonate and drilling mud
As an oil contamination resistance agent in paper production.
In foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans.
