Sodium Hexa Meta Phosphate (CAS 10124-56-8) is an inorganic polymer salt supplied as a white granular solid with a declared 68% P2O5 content that sequesters multivalent metal ions such as calcium and magnesium and is used in boiler water treatment, food processing and detergent manufacture. It is highly valued for its exceptional sequestration properties, effectively binding with multivalent metal ions like calcium and magnesium to prevent scaling and precipitation.
The product offers a high purity level of 68% P2O5, ensuring superior efficiency in industrial and food-processing environments. Its unique molecular structure allows for excellent water solubility, making it a versatile additive for stabilizing dispersions and maintaining clarity in liquid formulations across various concentrations.
In commercial applications, SHMP acts as a powerful deflocculant and buffering agent, enhancing the texture and shelf-life of processed goods. Its ability to manage mineral content makes it an essential component for high-standard Boiler Water Treatment and sophisticated food preservation techniques.
