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 monitored. A comprehensive Certificate of Analysis (COA) detailing all specification results is 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). Keep away from heat sources and open flame. This product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption which can affect product performance.
