Polybenzimidazole Fiber

PBI fibers first became commercially available in 1983. Since that time the fibers have found wide usage in a number of areas. They are commonly utilized, for instance, in protective apparel, such as firefighter’s coats, rescue gear, space suits, and outer garments for hazardous materials workers. The fibers are also popularly included in industrial gloves and work wear, as well as race car driver uniforms. In molded plastic form, PBI is frequently utilized in brakes, gaskets, fuel cell membranes, and pump packing.
