Quality Control

Our production of this polycarbonate copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as molecular weight distribution, thermal properties, and intrinsic viscosity are rigorously controlled. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance with relevant industry standards for engineering polymers.

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, bases, and sources of heat or ignition to maintain polymer integrity. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect processing and final properties.
