Quality Control

Our copolyester polymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. All products undergo rigorous testing for key parameters including intrinsic viscosity, acid value, thermal properties (DSC/TGA), and color. Certificates of Analysis (COA) documenting these specifications are available upon request 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 room temperature (typically 15-25°C). Keep away from strong heat sources and open flames. As a precaution, store away from strong acids, bases, and oxidizing agents.
