Quality Control

Our polycarbonate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive testing including intrinsic viscosity, melt flow rate, thermal properties, and optical clarity. Certificates of Analysis (COA) detailing key specifications are provided with each shipment. We can supply grades compliant with various industry standards, including FDA, USP Class VI, and UL listings, upon request.

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 strong acids, strong bases, and organic solvents. As a hygroscopic (moisture-sensitive) polymer, the material should be kept in its original packaging until use to prevent moisture absorption, which can affect processing and final properties.
