Quality Control

Our production of this polyester polyol adheres to strict quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and color to ensure consistent performance in downstream formulations. While not a pharmaceutical ingredient, our quality system is designed to meet the rigorous demands of industrial polymer chemistry. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

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). Keep away from heat sources and open flame. Under recommended storage conditions, the product is stable for extended periods. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and contamination.
