Sodium Tripolyphosphate(STPP),sodium Tripolyphosphate,detergent raw material

Basic Information

Molecular formula:Na5P3O10 

Molecular weight  367.86

CAS number      7758-29-4

Properties

White powder,melting point 622,Easily soluble in water;it has got salient chelating capacity to irons of ca and mg etc.and can soften hard water to make suspension solution become into clear solution;it has got weak alkalinity but no corrosiveness.It is s surfactant,and has got outstanding emulsification to lubricants and fat.It has different bulk density.This product has two crystalline forms,namely type ithermostalility,hygroscopicity,solubility and hydration heat when dissolving.

Uses

Used as one of the main auxiliaries for synthetic detergent,synergist for soap,water softeren,tanning agent for leather making,auxiliary for dyeing,as an effective dispersion agent for

Suspension solutions of coatings,kaolin,magnesium oxide,calcium carbonate and drilling mud etc;

As an oil contamination  resistance agent in paper production.In foodstuff industry it is used as quality improver and softener or densifier.

Packing and storage

In 25kg,50kg,1000kg bag store at a cool,dry and well ventilated place
