Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical applications. While specific grades are tailored to customer requirements, all materials are characterized for key parameters such as molecular weight distribution, hydroxyl number, isocyanate content, and thermal properties. Certificates of Analysis (COA) detailing the specific specifications for your ordered grade are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). Ensure the original packaging remains sealed until use to prevent moisture absorption, which can affect processing and final product properties. Store away from heat sources and open flames.
