Quality Control

Our production of this polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While specific grades can be produced, typical quality assurance includes monitoring of key parameters such as acid value, viscosity, and thermal stability. Certificates of Analysis (COA) detailing the specifications for your ordered grade are 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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, the container should be opaque or stored in darkness.
