Quality Control

Our polyamide-imide polymer is manufactured under strict process controls to ensure batch-to-batch consistency and high performance. Quality is verified through a suite of analytical tests including viscosity, glass transition temperature (Tg), and thermal gravimetric analysis (TGA). A comprehensive Certificate of Analysis (COA) detailing key specifications is provided with every 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). This material is hygroscopic (moisture-sensitive); keep the original container sealed to prevent moisture absorption which can affect processing properties.
