Product Name: Sodium Tripolyphosphate (STPP) 94% Detergent Grade Most Competitive Price Model NO.: 94%min Grade Standard: Industrial Grade Type: Sodium Tripolyphosphate Purity: 90%~99% Certification: CIQ, ISO EINECS: 231-838-7 Formula: Na5p3o10 CAS No.: 7758-29-4 Trademark: Excelente Transport Package: 25kg/50kg/1000kg Bag Specification: 94%min Origin: China HS Code: 2835319000 Product Description Our advantagesManufacturer competitive priceGood qualityGood serviceGood reputationISO CertificateShort lead timeProduct description: Manufacturer supplies Sodium tripolyphosphate 94% technical gradeWhite 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 asurfactant, and has got outstanding emulsification to lubricants and fat.Production processPhosphoric acid and 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.ApplicationsUsed as one of the main auxiliaries for synthetic detergent, synergist for soap, water softener, tanning agent for leather making, auxiliary for dyeing. As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc. And as an oil contamination resistance agent in paper production.Package25kg/50kg/1000kgplastic woven bag, lined with PE bag,Technical Data sheet of Sodium Tripolyphosphate /STPP(industrial grade)IndexSpecificationAssay Na5P3O10 %≥94.0%P2O5≥57.0%Iron(Fe)≤0.01%pH9.2-10.2Phase I10-30%Bulk density0.35-0.95g/cm3Whiteness≥90.0Water Insoluble Matter≤0.10%Moisture≤1.0%
