Quality Control

Our production of this polyester polyol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our quality system is designed to support customers requiring materials for applications under ISO 9001 and other relevant quality frameworks.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
