Quality Control

Our production of this advanced polymer adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate content, hydroxyl value, viscosity, and molecular weight distribution are strictly monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade (typically between 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry atmosphere (e.g., nitrogen blanket) after opening to prevent moisture absorption and premature reaction.
