Quality Control

Our production of this specialty copolymer adheres to rigorous quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, acid value, glass transition temperature (Tg), and compositional analysis are strictly monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

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 flames. This polymer is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect processing characteristics.
