Quality Control

Our poly(amide-imide) polymer is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including inherent viscosity, glass transition temperature (Tg), and thermal gravimetric analysis (TGA). A comprehensive Certificate of Analysis (COA) detailing key specifications is provided with each 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 room temperature (15-25°C). Keep away from strong acids, bases, and sources of ignition. As a polymeric material, prolonged exposure to high humidity should be avoided to prevent potential property changes.
