Quality Control

Our Poly(1,4-Phenylene Ether-Ether-Sulfone) is manufactured under stringent quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a comprehensive suite of analytical tests, including intrinsic viscosity, thermal analysis (DSC, TGA), and mechanical property assessment. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). To prevent moisture uptake and potential property degradation, the original packaging should be kept sealed until use.
