Polyacrylonitrile (PAN) Filament is a high-performance synthetic fiber derived from the polymerization of acrylonitrile monomers. It is the filament form of PAN fiber, characterized by continuous strands with excellent mechanical and chemical properties. PAN filament plays a pivotal role in industries such as textiles, carbon fiber precursor manufacturing, composites, and filtration, due to its outstanding strength, thermal stability, and chemical resistance.
