Quality Control

Our production of this polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance processes.

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). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
