Used primarily in the production of synthetic fibers, it is a key component in making textiles for clothing, home furnishings, and industrial fabrics. Its high strength and resistance to chemicals make it suitable for creating materials used in outdoor and protective gear. Additionally, it serves as a precursor for carbon fiber, which is essential in manufacturing lightweight, high-strength composites for aerospace, automotive, and sports equipment industries. It also finds applications in filtration systems due to its ability to form membranes with fine porosity.
