Quality Control

Our Polyacrylonitride is produced under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as molecular weight distribution, viscosity, and residual monomer content are rigorously controlled. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); protect from humidity to prevent clumping or degradation of properties. Keep away from strong oxidizing agents.
