Product Description
Sodium Tripolyphosphate STPP Property:
White powder or granular solid, soluble in water, which complexing ability to alkali metal and metal salt,It can soften water, adjust and buffer the PH value of saponification value, 1% solution PH value of 9.7 with ion exchange ability.
Sodium Tripolyphosphate STPP Application:
Sodium tripolyphosphate has chelating, suspending, dispersing, gel dissolving, emulsifying, pH buffering and other functions. It can be used as auxiliary agent of synthetic detergent, industrial water softener, leather pre-tanning agent, dyeing assistant, organic synthesis catalyst, dispersing agent of medical industry and food additive.At present, its largest use is still as a powder synthetic detergent additives and Ceramic Degumming Agent.
