Property:

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.

Application Information

Characteristics: Salient chelating capacity to metal ions of Ca and Mg etc.

Soften hard water to make suspension into solution, alkalinity, without causticity.

Outstanding emulsification to lubricants and fat.

Application Field:

n STPP is widely used as one of the main auxiliaries for synthetic detergent,

synergist for soap;

n Water softener, tanning agent for leather making, auxiliary for dyeing;

n In ceramics, distribute clay evenly

n STPP is also used as an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.;
