Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, acid value, glass transition temperature (Tg), and melting point are rigorously controlled. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 room temperature (15-25°C). Keep away from strong heat sources and open flames. This polymer is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption which can affect processing properties.
