Quality Control

Our Poly(Oxy-1,2-Ethanediyloxycarbonyl-2,6-Naphthalenediylcarbonyl) is manufactured under a strict quality management system. Each batch undergoes rigorous testing for intrinsic viscosity, thermal properties (DSC/TGA), color, and residual monomer content to ensure it meets precise customer and industry specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 sources of extreme heat. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which can affect processing characteristics.
