Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like molecular weight, viscosity, and hydroxyl value. Quality is verified through a suite of analytical techniques including GPC, FT-IR, and titration methods. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance in regulated supply chains.

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). Keep away from heat sources and open flame. This material is moisture-sensitive; ensure containers are sealed after each use to prevent absorption of atmospheric moisture which can affect product properties.
