Description

Sodium tripolyphosphate is a white powder material with melting point **2 ℃, which is soluble in water with significant chelating capacity to calcium and magnesium and other metal ions, it can soften hard water to make suspension into solution. Features: slightly alkaline, non-corrosive, sodium tripolyphosphate is an inorganic surfactant, which has strong emulsification with lubricating oil and fat, bulk density is usually divided into a low density 0.***0.5g / cm 3, medium density of 0.***0.*5g / cm 3, high density 0.***0.9g / cm 3.

Sodium tripolyphosphate have two crystalline forms: type I (high temperature type) and type II (low temperature type), both with the same chemical properties, type I thermal stability and moisture difference is higher than that of type II, and the solubility, dissolution heat of hydration is also different between them.
