Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, acid value, glass transition temperature (Tg), and melting point are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep away from strong oxidizing agents, strong acids, and strong bases.
