Quality Control

Our production of this high-performance copolyester adheres to strict quality management systems, ensuring batch-to-batch consistency for critical engineering applications. Key parameters including intrinsic viscosity (IV), glass transition temperature (Tg), melt flow index (MFI), and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from sources of heat and open flame. Under these conditions, the product remains stable for extended periods. Ensure the original packaging is kept sealed until use to prevent moisture absorption.
