Quality Control

Our production of this multi-component copolyester adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity (IV), acid value, glass transition temperature (Tg), and thermal stability are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from strong acids, strong bases, and organic solvents. As a polymer, protect from excessive heat and moisture to prevent clumping or property degradation prior to use.
