Product Description

Experience Unmatched Quality with Our 94% Pure Sodium Tripolyphosphate (STPP) - Essential for Detergents, Paints, and Industrial Wastewater Treatment

Our Sodium Tripolyphosphate boasts a pristine white powder crystal form, renowned for its excellent fluidity. Available in two types: Type 1 with a density of 2.62g/cm³, and Type 2 with a density of 2.57g/cm³. With a melting point of 622ºC, this compound is highly soluble in water, forming an alkaline aqueous solution.

Solubility: Highly Soluble in Water, 20g/100mL at 20ºC

Sodium triphosphate (STPP or sodium tripolyphosphate) is a versatile inorganic compound with the chemical formula Na5P3O10. As the sodium salt of the polyphosphate penta-anion, it acts as the conjugate base of triphosphoric acid. This compound is mass-produced for inclusion in a broad range of domestic and industrial applications, most notably
Detergents.
Widespread use of this compound has been linked to environmental challenges, particularly eutrophication.

Sodium Tripolyphosphate Application

Product Application

1. STPP tech grade serves as an essential additive in detergent synthesis, ceramics production, and as a soap synergist.
2. Exhibits robust emulsifying properties for lubricants and fats, and aids in adjusting the pH level of buffer liquids in soaps.
3. Functions as a water softener and buffering agent within the detergent industry.
4. Acts as a quality modifier, pH adjuster, water retaining agent, and performs various roles within the food industry.
5. Integral in the paper-making process.
6. Operates as a dispersing agent in oil drilling mud, enhancing efficiency.
7. Widely used in the ceramic, mining, and water treatment industries, among others.

Function in Detergent Industry:

STPP serves as an excellent auxiliary in the detergent industry, with a typical usage rate of 10-35%. The key functions of STPP in a detergent system include:

1. Softening hard water by reacting with metal ions such as Ca²⁺, Mg²⁺, Fe³⁺and others, transforming them from insoluble to soluble. Na₅P₃O₁₀+Ca²⁺ --->Na₃(CaP₃O₁₀)+2Na⁺
2. Enhancing emulsification and dispersion, thereby increasing the solubility of proteins and dust commonly found in fabrics.
3. Acts as a buffering agent, maintaining the detergent solution's pH at around 9~9.5, which facilitates the removal of acidic dirt from fabrics.
4. Serves as an anti-caking agent for detergent powders. It absorbs moisture, transforming into Hexahydrate, which remains dry and free-flowing.
