Sodium Tripolyphosphate STPP


Executive Standard: GB25566-2010                                          
Molecular Formula: Na5P3O10                  CAS No.:7758-29-4
MW: 367.86 
Character: It is white powder; Byname is Pent-sodium Phosphate; Melting point is 622°C;It has salient chelating capacity to ions of Ca, Mg etc; It can soften the hard water to make suspension become into the clear solution; it has weak alkalinity but no corrosiveness. It is a surfactant which has outstanding emulsification for lubricants and fat; It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3.This product has two kinds of crystalline forms, namely Type I (the type of high temperature) and Type II (the type of low temperature). The chemical characters of the two types are the same, and the difference between them lies in the thermo stability
Package: 25kgs woven bag lined with plastic bag, according to the customer’s demand ,Stored at draughty dry places.
Usage: In the food industry used as the quality modifying agent and water retention agent in canned food, fruit juice, soy milk and other dairy products; mainly for canned ham tender, broad beans in the skin softening, it can also be used as a thickening agent and softening agent.
