Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of analytical tests, including determination of solid content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can tailor specifications to meet specific customer or application standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, consider using under an inert atmosphere to prevent oxidation or moisture uptake, which could affect polymer properties.
