Quality Control

Our production of this aromatic copolyester adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, thermal transition temperatures (Tg), and residual monomer content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with each shipment to support your quality assurance processes.

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 should be kept dry to prevent any potential hydrolysis or property degradation before processing.
