Our commitment to quality, advanced production technology and strict quality control system has made us a trusted partner for businesses in various industries worldwide. This page provides a detailed introduction to our sodium hexametaphosphate, helping you understand its properties, applications, specifications and our competitive advantages.
1. Product Overview
Sodium Hexametaphosphate, commonly abbreviated as SHMP, is an inorganic compound with the chemical formula Na₆O₁₈P₆ (or (NaPO₃)₆) and a molecular weight of 611.77. Also known as Graham’s salt, it is a polymer of sodium metaphosphate, presenting as white crystalline powder, colorless transparent glassy lumps or flaky solids under normal temperature and pressure. It is highly hygroscopic, easily soluble in water with an alkaline aqueous solution, and insoluble in organic solvents such as ethanol and ether. With excellent chelating, dispersing and anti-flocculating properties, SHMP is widely used in food, industrial water treatment, textile, paper making, petroleum and other fields.
2. Physical & Chemical Properties
Appearance: White crystalline powder, colorless transparent glassy lumps or flakes, odorless
Density: Approximately 2.181 g/cm³
Melting Point: 616℃ (decomposes at melting point)
Solubility: Easily soluble in water; solubility is 973.2 g/L at 20℃, and increases with temperature rise; insoluble in ethanol, ether and other organic solvents
Hygroscopicity: Highly hygroscopic, absorbing moisture in the air to form viscous substances and undergoing hydration reaction to generate sodium pyrophosphate
Chemical Stability: Relatively weak; easily decomposes into orthophosphoric acid when exposed to warm water, acid or alkaline solutions
Key Feature: Strong chelating ability, capable of forming soluble complexes with calcium, magnesium, iron and other metal ions, effectively preventing the crystallization of these salts in solutions
3. Wide Applications
Benefiting from its unique properties, our sodium hexametaphosphate is widely used in multiple industries, providing high-performance solutions for our customers:
3.1 Food Industry
As a food additive that meets national and international standards (GB 1886.4-2020), SHMP is widely used in food processing with multiple functions:
Meat products (sausages, ham, meatballs): Improves water retention and binding capacity, prevents fat oxidation, and maintains the tenderness and juiciness of meat
Fruit drinks, cold drinks and dairy products: Enhances viscosity, improves juice yield, inhibits vitamin C decomposition, and prevents gel precipitation
Soy sauce, bean paste: Prevents discoloration, increases viscosity, shortens fermentation period and adjusts taste
Ice cream: Improves expansion capacity, prevents texture damage, and enhances emulsification effect to improve taste and color
Canned fruits and vegetables: Stabilizes natural pigments, protects food color and extends shelf life
3.2 Industrial Water Treatment
SHMP is an efficient water softener and scale inhibitor, widely used in various industrial water treatment scenarios:
Boiler water, chemical production water, dyeing and printing water: Softens water by chelating calcium and magnesium ions, preventing scale formation and protecting equipment from corrosion
EDI, RO, NF water treatment systems: Serves as a scale inhibitor to improve water treatment efficiency and extend the service life of membrane elements
Industrial circulating cooling water: Acts as a water treatment agent to prevent scale deposition and equipment corrosion, improving heat transfer efficiency
3.3 Other Industrial Fields
Textile & Dyeing Industry: Used as a water softener and dispersant, ensuring uniform dyeing and improving product quality
Paper Making Industry: Serves as a dispersant, improving the uniformity of pulp and enhancing paper strength
Petroleum Industry: Used as a mud conditioner in oil drilling to adjust mud viscosity and prevent drill pipe rusting
Metal Processing: Acts as a corrosion inhibitor and metal preservative, protecting metal surfaces from oxidation and corrosion
Detergent Industry: Used as an auxiliary agent to enhance decontamination effect and improve washing efficiency
