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 color are rigorously monitored. Certificates of Analysis (COA) detailing lot-specific specifications are available upon request, supporting compliance with relevant industry standards for polymer materials.

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 heat sources and open flame. As with many polymeric materials, prolonged exposure to high humidity or extreme temperatures should be avoided to maintain product integrity.
