Quality Control

Our production of Poly((1,6-Bis(p-Carboxyphenoxy)Hexane) adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including inherent viscosity, thermal transition temperatures, and residual monomer content. Certificates of Analysis (COA) detailing these specifications are provided and we support compliance with relevant regulatory frameworks for target applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to prevent hydrolysis and degradation of polymer properties.
