Quality Control

Our Aluminum Oxide Hydroxide is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Production adheres to relevant industrial standards, with critical parameters including Al2O3 content, particle size distribution, and loss on ignition (LOI) being rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
