Quality Control

Our production of this advanced copolyester adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like intrinsic viscosity, glass transition temperature (Tg), and color. Each lot is characterized using advanced analytical techniques including GPC, DSC, and FTIR to verify polymer structure and purity. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is 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 a controlled room temperature (15-25°C). Keep the original packaging sealed until use to prevent moisture absorption, which can affect processing characteristics. Store away from strong oxidizing agents and heat sources.
