Quality Control

Our Cyclic Olefin Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including intrinsic viscosity, glass transition temperature (Tg), residual monomer content, and optical properties to ensure consistent performance and compliance with industry specifications. Certificates of Analysis (COA) detailing all test results are available upon request.

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 oxidizing agents and heat sources to maintain polymer integrity.
