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 (IV), acid value, glass transition temperature (Tg), and color are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are available upon request, and we can support compliance with REACH, FDA (for indirect food contact applications, where applicable), and other regional regulatory frameworks.

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 heat sources and incompatible materials such as strong acids, strong bases, and strong oxidizing agents.
