Molecular formula:Na5P3O10Molecular Weight: 367.86 hs code: 2835.3100

Cas no.: 7758-29-4

 

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 stabilityPackage: 25kgs woven bag lined with plastic bag, according to the customers demand ,Stored at draughty dry places.

Usage: It is used as one of the main auxiliaries agent for synthetic detergent, synergist for soap; Tanning agent for making leather; Softener for water in industry; An effective dispersion agent for suspension treatment of painting, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.;Resistance agent of the oil contamination in paper production.
