Quality Control

Our Poly(1,4-Phenylene Ether-Sulfone) is manufactured under a strict quality management system. Each batch is tested for key parameters including intrinsic viscosity, thermal properties (Tg), and mechanical strength to ensure consistency and performance. Certificates of Analysis (COA) detailing lot-specific results are available upon request.

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 sealed to prevent moisture absorption which can affect processing.
