Celanese PBI is a derivatized polybenzimidazole fiber possessing a unique balance of properties that permit it to meet critical cost/performance criteria in demanding environments. The fiber, a modification of previously documented earlier versions, has excellent textile, tactile, thermal, and chemical resistance properties and sig nificantly reduced flame shrinkage, all of which are fully described. These properties permit the fiber to be used as an alternative to asbestos, in high temperature… 
Polibenzimidazol (PBI) Lifleri
Polybenzimidazole (PBI) fibers are produced from polybenzimidazole polymer which has a high thermal and chemical strength with a long chain aromatic structure. These fibers are first used in
History and Development of Polybenzimidazoles
Aromatic polybenzimidazoles were synthesized by H. Vogel and C. S. Marvel in 1961 with anticipation, later justified, that the polymers would have exceptional thermal and oxidative stability.
PBI (Polybenzimidazole): Synthesis, Properties and Applications
PBI (polybenzimidazole) is a thermally stable high performace polymer. In a variety of forms, e.g. fibers, neat resin and composites, PBI finds use in a wide range of high temperature applications.
High‐modulus polyaramide and polybenzimidazole blend fibers
Polymer blends from polybenzimidazoles (PBI) and high-performance polyaramides were spun to give a PBI variant with better tensile properties than PBI itself. Infrared absorption spectra of a
Polybenzimidazole and polysulfone blends
Polybenzimidazole (PBI) and polysulfone (PS) do not form miscible blends; however, the tensile modulus and strength of their blend fibers are comparable to, or better than, that of PBI fibers,

The effect of lithium chloride on polybenzimidazole and polysulfone blend fibers
Poly[2,2'-(m-phenylene)-5,5'-bibenzimidazole] (PBI) and polysulfone (PS) [OPhC(Me) 2 PhOPhSO 2 Ph] n do not form miscible blends; however, the tensile properties of the polymer blend in fibers, and
Solution polymerization of polybenzimidazole
Polybenzimidazoles (PBI) are an important class of heterocyclic polymers that exhibit high thermal and oxidative stabilities. The two dominant polymerization methods used for the synthesis of PBI are


PBI Fiber and Fabric—Properties and Performance
Polybenzimidazole (PBI) is the only textile fiber, either commercial or developmental, which under normal conditions is nonflammable in air, emits little or no smoke, and produces virtually no toxic
