Quality Control

Our Polyacrylonitrile, Partially Carbonized is produced under controlled conditions to ensure batch-to-batch consistency for critical industrial applications. Quality is verified through a suite of analytical tests, including elemental analysis (C, H, N, O content), thermal gravimetric analysis (TGA) to confirm carbonization degree, and infrared spectroscopy (FTIR) for structural verification. Certificates of Analysis (COA) detailing specific parameters are available upon request 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). This material is hygroscopic (moisture-sensitive); protect from excessive humidity to prevent agglomeration or property changes. Keep away from strong oxidizers.
