Content
Sodium tripolyphosphate is a white powder with a melting point of 622°C. It has significant chelating ability to metal ions such as calcium and magnesium ions. It can soften hard water and turn suspension into a solution. It is weakly alkaline and non-corrosive. It is an inorganic surfactant. It has a strong emulsification effect on lubricating oil and fat. Bulk density is usually divided into low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3, and high density 0.66-0.9g/cm3.
