Polybenzimidazole fiber
PBI Performance Products
PBI (polybenzimidazole) stable fiber is an organic fiber that provides thermal stability for a wide range of high temperature applications. PBI fiber will not burn in air, it does not melt or drip, and it will retain its strength and flexibility after exposure to flame. Stable Fiber is currently available as a nominal 1.7 denier/filament (dpf) in 1/4 inch, 2 inch, 3 inch, and 4 inch fiber lengths.
As the backbone of various flame resistant fabric blends, PBI fiber enhances the performance of complementary fibers, combining flame-resistance and thermal protection with the highest level of comfort, durability, and protection available in the world.
