Quality Control

Our production of this polyamide copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including intrinsic viscosity, melting point, amine end-group concentration, and thermal stability. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

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 packaging sealed until use to prevent moisture absorption, which can affect processing and final properties.
