1.Product description:
 

Name: Sodium Tripolyphosphate (ceramic grade 94% sodium tripolyphosphate/STPP Chemical)

Molecular Formular: Na5P3O10 

Molecular Weight : 368

Shelf Life: 2 years

CAS No.: 13573-18-7 

Appearance: White powder or granular; Easily soluble in water;

Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, 

NaH2PO4, under carefully controlled conditions.

2 Na2HPO4 + NaH2PO4 → Na5P3O10 + 2 H2O

In this way, approximately 2 million tons are produced annually.ceramic grade 94% sodium tripolyphosphate/STPP Chemical is a colourless salt, which exists both in anhydrous form and as the 

hexahydrate. The anion can be described as the pentanionic chain [O3POP(O)2OPO3]5-.Many related di-, tri-, and polyphosphates are known including the cyclic triphosphate P3O93-. It binds strongly to metal cations as both a bidentate and tridentate chelating agent.

4.Product uses:
 

In detergents

The majority of ceramic grade 94% sodium tripolyphosphate/STPP Chemical is consumed as a component of commercial detergents.It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly chargedchelating agent, TPP5- binds to dications tightly and prevents them from interfering with the sulfonate detergent.

 

Food applications

ceramic grade 94% sodium tripolyphosphate/STPP Chemical is a preservative for seafood, meats, poultry, and animal feeds.It is common in food production as E number E451. In foods, ceramic grade 94% sodium tripolyphosphate/STPP Chemical is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists ceramic grade 94% sodium tripolyphosphate/STPP Chemical as "generally recognized as safe.".

 

Other uses

Other uses (hundreds of thousands of tons/year) include "ceramics, leather tanning(as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze.Tech Grade White Powder/Granule 94% Sodium Tripolyphosphate STPP
