Quality Control

Our copolyester resins are produced under strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as intrinsic viscosity (IV), color, thermal properties (DSC), and mechanical strength are rigorously tested. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance with relevant industry standards.

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 strong oxidizing agents and excessive heat sources to maintain polymer integrity. The material is hygroscopic (moisture-sensitive); original packaging should be kept sealed until use.
