Used primarily in the production of acrylic fibers for textiles and clothing due to its softness, warmth, and wool-like feel. Commonly found in carpets, blankets, and outdoor fabrics because it resists sunlight degradation and abrasion. Serves as a precursor for carbon fiber production, which is essential in aerospace, automotive, and sporting goods industries for lightweight, high-strength materials. Also utilized in filtration membranes for water treatment and in some battery components due to its chemical stability and ability to form porous structures.
