In the textile industry PBI fiber is witnessing strong demand as they retain their strength without infringement even when exposed to extreme higher temperatures. In any case, under outrageous conditions, the fiber emanates little smoke.
Additionally, the better thermal stability of polybenzimidazole enhances its demand in high-performance protective apparel such as protective gloves, firefighter’s gear, welders’ apparel, astronaut space suits, and aircraft wall fabrics. PBI is also used as a plastic reinforcements, for heat and chemical resistant filters, and for various other civil engineering applications. The fiber is often blended with other high performance fibers like Kevlar®.
