94% Sodium Tripolyphosphate(STPP)
Our Advantages
In terms of metal ion chelation, our sodium tripolyphosphate Granular exhibits outstanding coordination capabilities for calcium, magnesium, iron, and other metal ions (calcium chelation value ≥ 300 mg CaCO₃/g), effectively preventing scale formation and equipment corrosion. Its superior dispersing properties help suspend particles stably, preventing redeposition—a critical feature in ceramic slurries and oilfield drilling fluids. As an emulsifying stabilizer, it significantly enhances the stability of oil-water systems, making it widely applicable in various industrial cleaning formulations.
Extensive Application Scenarios
In the detergent industry, sodium tripolyphosphate(STPP) serves as a traditional yet highly effective builder, significantly enhancing cleaning performance and softening water. In water treatment, it acts as an excellent water softener and corrosion inhibitor for cooling and boiler water systems.
In the food industry, food grade sodium tripolyphosphate(STPP) functions as a quality improver for meat and aquatic products. The ceramics industry utilizes its deflocculating properties to enhance raw material performance. Additionally, sodium tripolyphosphate(STPP) plays an irreplaceable role in textiles, printing and dyeing, paper making, oilfield chemicals, and many other fields.
