Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like melt viscosity, thermal transition temperatures, and mechanical strength. Certificates of Analysis (COA) are provided with each shipment, detailing key specifications. We support compliance with relevant global standards for polymers used in automotive (e.g., IATF 16949) and electrical applications.

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). This polymer is hygroscopic (moisture-sensitive). Keep the original packaging sealed until use to prevent moisture absorption, which can affect processing and final properties.
