Quality Control

Our polyamide resin is manufactured under a strict quality management system. Each batch is tested against key parameters including intrinsic viscosity, melting point, and residual monomer content to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the original container sealed until use to prevent moisture absorption, which can affect processing and final properties.
