What is a Polyacrylonitrile (PAN)?

Polyacrylonitrile (PAN) is a synthetic polymer made from acrylonitrile monomers and is widely used in fibers, films, and carbon fiber production. It offers excellent heat and chemical resistance, along with high mechanical strength, making it an essential material in both industrial and advanced applications. PAN fibers are known as acrylic fibers and are used in clothing for their lightweight and insulating properties. Carbon fibers derived from PAN through heat treatment are crucial in aerospace, automotive, and sports equipment due to their strength and lightness. While PAN is a stable polymer, care must be taken during processing to avoid exposure to residual acrylonitrile or thermal degradation. Proper ventilation and safety measures are recommended during handling and manufacturing. PAN is also gaining attention in precision fields such as battery materials, separation membranes, and filters, playing a key role in next-generation material technologies.
