Quality Control

Our production of this polyester polyol adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. Certificates of Analysis (COA) documenting full specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

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 / 59-77°F). Keep away from heat sources and open flame. This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect product performance.
