Product Description

STPP
 

Product description

Sodium tripolyphosphate 94% technical grade,White or  almost white granular or powder,easily soluble in water. Sodium tripolyphosphate has got salient chelating capacity to ions 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. Sodium tripolyphosphate is a surfactant, and has got outstanding emulsification to lubricants and fat.
 

Production process

Sodium carbonate react to generate Sodium dihydrogen phosphate and sodium hydrogen phosphate under certain temperature and pressure. Sodium dihydrogen phosphate and sodium hydrogen phosphate produce sodium tripolyphosphate by polymerization reaction under certain temperature, pressure and catalyst. Our process has been improved much gradually, saves costs,and increases the yield , so our price is very competitive.
