Polyacrylonitrile (PAN) is a synthetic acrylic polymer known for its strong fiber-forming capability and chemical resistance. It is widely used in textile applications—particularly acrylic fibers for apparel and home goods—as well as in composite reinforcement, carbon fiber precursors, and industrial membranes. Engineers select PAN for applications demanding good mechanical strength, thermal stability, and resistance to oils, solvents, and weathering, making it a cost-effective alternative to natural fibers and other synthetic polymers in many commodity and advanced applications.
