Quality Control

Our production of this advanced copolyester adheres to strict quality management systems, ensuring batch-to-batch consistency for our industrial partners. Key parameters such as acid value, hydroxyl value, viscosity, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant 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 heat sources and open flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent moisture absorption, which can affect product performance.
