Quality Control

Our production of this high-performance copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters including intrinsic viscosity, acid value, glass transition temperature (Tg), and thermal stability are rigorously monitored. Certificates of Analysis (COA) detailing lot-specific specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. The material should be kept under dry conditions to prevent moisture absorption which may affect processing characteristics.
