Quality Control

Our Aluminum Silicate is produced under a stringent quality management system to ensure batch-to-batch consistency and performance. Quality parameters including chemical composition, particle size distribution, and loss on ignition are rigorously tested. A Certificate of Analysis (COA) is provided with each shipment, and we can support compliance with relevant industry standards upon request.

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 moisture absorption and caking.
