Products Description
Polyacrylonitrile is a high‑performance synthetic polymer featuring outstanding thermal stability and chemical resistance. It acts as the principal raw material for producing high‑strength carbon fibers as a carbon fiber precursor. Within the textile sector, it is used to fabricate flame‑retardant fibers for protective garments and industrial textiles. It can also form robust filtration membranes suitable for water treatment and gas separation processes, and is incorporated into reinforced composites to manufacture components for automotive and aerospace industries.
