Quality Control

Our Sodium Metaphosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the required specifications for purity, composition, and physical properties. We can supply material compliant with FCC (Food Chemicals Codex) and other relevant industry standards. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
