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 acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color are rigorously monitored. 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent moisture absorption, which can affect product properties. Keep away from incompatible materials such as strong oxidizing agents.
