Quality Control

Our production of this high-performance copolyester adheres to strict quality management systems, ensuring batch-to-batch consistency for critical industrial applications. 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 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, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and excessive heat sources to maintain polymer integrity. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
