Manufacture Sodium tripolyphosphate 94% 97.5% For Detergent & Ceramic grade
Basic Info
Model No.: inorganic salt
Product Description
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compoundwith 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. Environmental problems associated with eutrophication are attributed to its widespread use.

Application:-
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 dications tightly and prevents them from interfering with the sulfonate detergent.
Effects of wastewater containing phosphorus
Detergents containing phosphorus contribute, together with other sources of phosphorus, to the eutrophication of many fresh waters. Eutrophication is an increase in chemical nutrients—typically compounds containing nitrogen or phosphorus—in an ecosystem. It may occur on land or in water.
The term is, however, often used to mean the resultant increase in the ecosystem's primary productivity (excessive plant growth and decay), and further effects including lack of oxygen and severe reductions in water quality and fish and other animal populations.
Other uses:-
Other uses (hundreds of thousands of tons/year) include ceramics (increase viscosity of the glazes up to a certain limit),
Leather tanning (as masking agent and synthetic tanning agent - SYNTAN),
Anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."
TPP is used as a polyanion crosslinker in polysaccharide based drug delivery.
