Quality Control

Our production of this polymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is characterized for critical parameters including monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications are provided and can be tailored to meet specific customer requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents. For long-term storage, consider using under an inert atmosphere to maintain polymer stability.
