Quality Control

Our production of this specialty copolymer adheres to a rigorous quality management system. Each batch is characterized for critical parameters including intrinsic viscosity, acid value, glass transition temperature (Tg), and residual monomer content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. The material is typically supplied in moisture-resistant packaging; once opened, containers should be resealed tightly to minimize exposure to atmospheric humidity.
