Quality Control

Our production of this polyurethane polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, viscosity, isocyanate content, and moisture are rigorously monitored. 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. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Ensure containers are kept sealed when not in use to prevent moisture absorption, which can affect product performance.
