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. Certificates of Analysis (COA) documenting all relevant specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). This product is moisture-sensitive (hygroscopic); keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
