PAN (polyacrylonitrile) is a synthetic acrylic polymer known for its high strength, rigidity, and thermal stability, commonly processed into fibers and films. It is widely used as a precursor material for carbon fiber production, as well as in acrylic fibers for textiles, filtration membranes, and protective coatings where chemical resistance and dimensional stability are required. Engineers select PAN-based materials for applications demanding lightweight strength combined with thermal performance and resistance to solvents and UV degradation, particularly in composites, aerospace, and industrial filtration.
