Product Description
Classification Sulphate Type Sodium Tripolyphosphate CAS No. 7758-29-4 Other Names Sodium Tripoly Phosphate; Sodium Tri Poly Phosphate MF Na5P3O10 EINECS No. 231-838-7 Place of Origin Hebei, China (Mainland) Grade Standard Industrial Grade, Reagent Grade Purity 94% Appearance White Powder or Granular Application detergent, cleaning industry,textile,leather etc Brand Name pangshi Model Number 94 Commodity Sulphate Sodium Tripolyphosphate STPP Sulphate Sodium Tripolyphosphate STPP Specification: Sodium Tripolyphosphate( STPP, STTP) Molecular Formular: Na5P3O10 Molecular Weight: 367.86 HS Code: 28353100 Industrial Grade: Main content: 94% Min P2O5: 57% Min Water Insoluble Matter: 0.1% Max Iron(Fe): 0.015% Max PH Value(1% wate solution): 9.2-10.0 Whiteness: 90% Min Ignition loss: 1.0 Density(g/cm3): 0.35-0.9 Phase I: 10-30 Detergent Grade: Main content: 94% Min P2O5: 57% Min Water Insoluble Matter: 0.1% Max Iron(Fe): 70 ppm Max PH Value(1% wate solution): 9.2-10.0 Whiteness: 88% Min Ignition loss: 1.0 Density(g/cm3): 0.65-0.9 Phase I: 10-30 Ceramic Grade: Main content 94% Min P2O5 57% Min Water Insoluble Matter 0.1% Max Iron(Fe) 0.015% Max PH Value(1% wate solution)9.2-10.0 Whiteness 92% Min Ignition loss1.0 Density(g/cm3)0.35-0.9 Phase I10-30 Application: Used as main auxiliary of synthetic wash, soap synergistic agent, water softener, leather pre-tanning agent, dye auxiliary agent, and dispersant of suspension such as paint, kaolin, magnesium oxide, calcium carbonate drilling mud, preservative agent for paper making, organic synthesis catalyze, also used in epuration of petroleum product, gum latex storage, as dispersant, solvent in metal industry and pharmaceutical industry. 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. Simple Production Methods: Purified Wet-process Phosphoric Acid Application
