Sodium polyphosphateCAS#68915-31-1

Excellent Water Solubility: This compound is readily soluble in water but insoluble in organic solvents, making it suitable for water-based applications.

Distinctive Physical Appearance: It appears as a colorless, transparent glass-like block or flake, providing clearly identifiable physical characteristics.

High Thermal Decomposition Temperature: It has a melting point of 616°C (with decomposition), indicating a high temperature threshold before decomposition occurs.

Strong Hygroscopic Properties: This compound readily absorbs moisture and can hydrolyze into orthophosphate in warm water or in acidic or alkaline solutions.

ABOUT THE PRODUCT

Product Description

Product Description-Sodium polyphosphateCAS#68915-31-1

Sodium polyphosphate appears as colorless, transparent glass-like blocks or flakes, soluble in water but insoluble in organic solvents. Highly hygroscopic, it readily hydrolyzes into orthophosphate in warm water or acidic and alkaline solutions, decomposes at its melting point of 616°C, and has a relative density (d₂₀/₂₀) of 2.484.

Product Applications-Sodium polyphosphateCAS#68915-31-1

Sodium polyphosphate acts as a preservative against bacteria, molds and yeasts, with high concentrations potentially causing skin irritation. Sodium hexametaphosphate, a form of polyphosphate, serves as a polyphosphate anion source for preparing hydrated calcium polyphosphate powder and a deflocculant for kaolinite and ceramic-grade kaolin suspensions, and also functions as sequestering and deflocculating agents primarily in water treatment, food processing, cleaning compounds and heavy-duty detergent builders.
