Quality Control

Our production of this copolyester adheres to rigorous quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters including intrinsic viscosity, acid value, glass transition temperature (Tg), and color are strictly monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

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 and organic solvents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed when not in use to prevent moisture absorption which may affect processing characteristics.
