Polyacrylonitrile fiber, commonly known as PAN fiber, is a synthetic fiber derived from the polymerization of acrylonitrile monomers. It is a type of acrylic fiber and possesses high strength, excellent chemical resistance, and thermal stability.
PAN fiber is commonly used in the production of NAO formulations for brake pads and linings. It is utilized as a reinforcement material to enhance the mechanical properties and performance of the friction material.
| Fiber length (Typical) | Fiber diameter (Typical) | |
| r pan 1,2 | 95% passing 1200 μm mesh | 30 microns |
| r pan 250 | 75 – 175 μm (>50%) | 1,1 – 5,5 dtex (>95%) |
