We offer our customers a wide range of STPP, which are available following Specifications :- Molecular Formula: Na5P3O10 MW: 367.86 Description: Name: Pent-sodium Phosphate(STPP) It is white powder. Melting point is 622A C. It is easily soluble in water. 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 STPP 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 It is used as one of the main auxiliaries agent for synthetic detergent, synergist for soap.
