Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in molecular weight distribution, sulfonation degree, and thermal properties. Certificates of Analysis (COA) detailing key specifications are provided with every shipment to guarantee it meets your precise formulation requirements.

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); ensure the container is kept sealed to prevent absorption of atmospheric moisture, which can affect handling and performance.
