Quality Control

Our polycarbonate-polyurethane copolymer is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance. We adhere to ISO 9001 quality management standards, with critical parameters including molecular weight distribution, hydroxyl value, and isocyanate content rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent degradation of reactive end groups. Keep away from strong acids, bases, and oxidizing agents.
