Quality Control

Our production of this high-performance polymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, Thermal Gravimetric Analysis (TGA) for thermal stability, and spectroscopic methods for structural confirmation. A comprehensive Certificate of Analysis (COA) detailing key specifications is provided with every shipment.

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). The product is hygroscopic (moisture-sensitive); keep the original container tightly sealed when not in use to prevent moisture absorption, which can affect processing properties. Keep away from strong acids, bases, and oxidizing agents.
