Sodium tripolyphosphate/ STPP
Industrial grade 96% CAS 7758-29-4
Food grade 85% CAS 7758-29-4
Molecular formula Na5P3O10
Molecular weight 367.86
【 Performance Characteristics 】
White granular or powder, showing a density of 0.35-0.90G/CM3, melting point 622 degrees Celsius.
It is easily soluble in water, the aqueous solution is alkaline, and the PH of 1% aqueous solution is 9.7.
It is gradually hydrolyzed into phosphite in water, and has good ionic ability of metal complexation.
It can be complexed with calcium/magnesium/iron and
other metal ions to produce soluble complexes. It softens hard water. As a kind of inorganic surfactant,
it has some properties of organic surfactant.
"Three-in-one" industrial solution
Cost savings: 1 ton of STPP has the same efficiency as 1.2 tons of common phosphate
Improve efficiency: The flow time of ceramic slurry is reduced from 120 seconds to 72 seconds
Risk control: Full REACH pre-registration document support
Why choose our sodium tripolyphosphate?
High purity (96%) - Ensures industrial application effect

Safety Tips:
Avoid inhaling dust. Wear protective masks and gloves when operating.
Keep away from strong acids and prevent violent reactions.
In case of contact with eyes or skin, rinse immediately with plenty
of water and seek medical attention.
Storage conditions
Store in a cool and dry place in a sealed container to
prevent moisture and caking.
Shelf life: 24 months.
Outstanding chelating ability
One gram of STPP can chelate ≥200mg of calcium ions (laboratory data), significantly reducing water hardness
Compared with traditional phosphates, the metal ion binding efficiency has increased by 35%
Multi-form adaptation
It is available in two forms: powder (0.1-0.5mm) and granules (0.5-1.2mm)
Customized particle size meets different process requirements such as spray drying and direct mixing
Composite function enhancement
It has the triple functions of dispersion, emulsification and pH buffering
It has a synergistic effect with surfactants to reduce the overall usage cost
