Quality Control

Our production of this copolyester adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance. Key parameters such as intrinsic viscosity, acid value, thermal transition temperatures, and monomer composition are strictly monitored. Certificates of Analysis (COA) detailing these specifications are available for every batch upon request. We operate under a quality management system aligned with industrial best practices to meet the precise requirements of our global B2B clients.

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 polymer is hygroscopic (moisture-sensitive); keep the original packaging sealed to prevent moisture absorption, which can affect processing and final properties. Keep away from strong heat sources and open flames.
