Quality Control

Our Polycarbonate Resins are manufactured under stringent process controls to ensure batch-to-batch consistency and meet the high standards required for engineering applications. Quality is verified through a comprehensive suite of tests including intrinsic viscosity, melt flow rate, thermal properties, and mechanical strength analysis. Certificates of Analysis (COA) detailing key parameters are 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 acids, bases, and organic solvents. As a hygroscopic material, it should be kept in original packaging until use to minimize moisture absorption.
