Quality Control

Our Imide Resin is manufactured under a stringent quality management system. Each batch is tested to ensure consistency in key parameters such as molecular weight distribution, glass transition temperature (Tg), and inherent viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 acids, bases, and sources of ignition. The resin may be hygroscopic; prolonged exposure to high humidity should be avoided to prevent moisture absorption which can affect processing.
