Quality Control

Our Boric Acid, Aluminum Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance as a flame retardant additive. Key parameters such as assay, particle size distribution, and moisture content are verified. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your specifications.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong acids and strong oxidizing agents.
