Types of Sodium Hexametaphosphate
Core Technological Advantages:
- Superior Chelating Ability: Effectively binds calcium, magnesium, and other metal ions, preventing scaling and precipitation.
- High Dispersion Power: Acts as a potent dispersant, maintaining uniform suspension in ceramic slurries and coatings.
- pH Buffering Ability: Stabilizes the pH in complex chemical formulations.
- Moisture Retention: Crucial for increasing yield in meat and seafood processing.
What is Sodium Hexametaphosphate Used for
- Food Industry: Enhances texture, moisture retention, and shelf life in meats, dairy, and beverages.
- Water Treatment: Prevents scale and corrosion in boilers and cooling systems via metal chelation.
- Detergents: Acts as a builder to boost cleaning efficiency and prevent dirt redeposition.
- Ceramics: Serves as a dispersant and deflocculant to improve slurry flow and reduce viscosity.
- Textiles: Improves dye uptake and wash-fastness during fabric processing.
- General Industry: Used in paper manufacturing, oil drilling, and as a corrosion inhibitor.
FAQ of Sodium Hexametaphosphate
The main difference lies in the impurity thresholds. Food-grade (E452i) must meet strict limits on heavy metals (lead ≤ 1 ppm, arsenic ≤ 3 ppm) and fluorine content, while industrial-grade is optimized for the utilization efficiency of phosphorus pentoxide (P₂O₅) in industrial processes.
SHMP reacts with calcium and magnesium salts in water to form soluble complexes. This prevents these minerals from precipitating as hard calcium carbonate or magnesium silicate scale on pipe walls.
Yes. Our production facilities are ISO 9001 certified, and our Food Grade SHMP meets FCC (Food Chemicals Codex), REACH, Halal, and Kosher requirements.
No, Sodium Hexametaphosphate is generally classified as non-hazardous for transport. However, like all industrial chemicals, it should be handled with standard PPE (gloves and goggles) to avoid skin or eye irritation.
The shelf life is typically 2 years from the date of manufacture. Because SHMP is hygroscopic (absorbs moisture from the air), it must be stored in a cool, dry, and well-ventilated area in its original sealed packaging to prevent caking or hydrolysis into orthophosphate.
SHMP Packaging
Standard: 25kg/bag.
Custom: 500kg/1000kg jumbo bags or tailored solutions.
SHMP Storage
Environment: Cool, dry, and well-ventilated.
Caution: Keep tightly sealed. SHMP is highly hygroscopic; moisture causes caking and degradation.
