94% STPP additive powder Specifications Sodium Tripolyphosphate - STPP 1, Industrial grade 2, Additive of Detergent 3, Water softener 4, We can supply best service. Sodium triphosphate (STP, sometimes STPP or sodium tripolyphosphate or TPP,) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. 25kg/pp bag 21mt/20G'P.
White powder, apparent density:0.35-0.90g/ml, melting point: 622�°C, easily dissolving in water; water solution is alkaline (PH value of 1% solution is 9.7); can hydrolyze into phosphate in water, has good ability in complexing metal ions; can be used to soften water; has some surfactant properties. 1.In detergents The majority of STPP 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 charged chelating agent, TPP5- binds to dictations tightly and prevents them from interfering with the sulfonate detergent. 2.Food Applications STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP 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 STPP as "generally recognized as safe.". 3.Other Uses Other uses (hundreds of thousands of tons/years) 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.
it is white powder, 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 is used as one of the main auxiliaries agent for synthetic detergent, synergist for soap, tanning agent for making leather, softener for water 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. 25kg/plastic woven bag, 23mt/20'FCL.

It is a surfactant, and has got outstanding emulsification to 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 crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermo stability, hygroscopic, solubility and hydration heat when dissolving. Uses: Used 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.; As an oil contamination resistance agent in paper production. In foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry. Packing And Storage: In 25Kg/50 Kg net bag, store at a cool, dry and well ventilated place.
