Frequently asked questions
What is sodium metaphosphate commonly used for?
Sodium metaphosphate is primarily used as a sequestrant in detergents, a food additive (E452) for emulsification and pH control, and in industrial water treatment to prevent scale buildup.
What is the chemical formula and molecular weight of sodium metaphosphate?
The chemical formula is **(NaPO₃)ₙ** (a polymeric form), but the exact molecular weight (MW) varies by chain length and is not fixed.
How should sodium metaphosphate be stored?
Store in a cool, dry place at **ambient temperature**, away from moisture and incompatible substances, in a tightly sealed container.
What grades of sodium metaphosphate does Molekula supply?
Molekula supplies **technical/industrial grade** sodium metaphosphate, suitable for detergents, water treatment, and general industrial applications.
Can Molekula supply sodium metaphosphate in bulk quantities?
Yes, we offer **bulk packaging options** (e.g., 25kg bags, 1MT big bags) for large-scale industrial and commercial customers—please inquire for specific availability.
What documentation comes with a sodium metaphosphate order?
Each order includes a **Certificate of Analysis (CoA)**, Material Safety Data Sheet (MSDS), and a packing list; additional documentation like a **Certificate of Conformity (CoC)** may be provided upon request.
