Quality Control

Our Acrylonitrile/Butadiene Copolymer is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. We provide comprehensive quality assurance, including testing for acrylonitrile content, Mooney viscosity, and residual monomers. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality and regulatory compliance needs.

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 sources of heat, ignition, and strong oxidizing agents. For long-term storage, maintain under an inert atmosphere to prevent oxidation and maintain polymer integrity.
