PAN Powders

Product Description

Polyacrylonitrile (PAN) powders are fine, white thermoplastic polymer powders composed primarily of polyacrylonitrile chains. Known for their excellent thermal stability, chemical resistance, and mechanical strength, PAN powders are indispensable in high-performance material applications. Depending on the polymerization approach, PAN powders are classified into homopolymers and copolymers, and they can be produced by dry or wet spinning techniques.

Insoluble in water but readily soluble in organic solvents such as DMF, DMSO, DMAc, and NMP, PAN powders are widely used in the production of acrylic fibers, ultrafiltration membranes, electrospun nanofibers, and as precursors for carbon fiber. They are also valuable as modifiers for plastics and rubber materials.

Alfa Chemistry offers high-quality PAN powders, tailored to meet diverse industrial needs in textiles, filtration, aerospace, advanced composites and other industries. With a commitment to consistent quality and reliable supply, we support innovation across a range of high-performance applications.
