Quality Control

Our polyimide polymers are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot undergoes comprehensive analysis, including determination of inherent viscosity, thermal properties (Tg, Td), and residual solvent content. Certificates of Analysis (COA) detailing all relevant specifications are 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 tightly sealed to prevent moisture absorption, which can affect processing and final properties.
