Description
A thermoplastic polymer that is stable at high temperatures. Polybenzimidazole (PBI) is made from the reaction of diphenyl isophthalate with diaminobenzidine. It is is primarily used to produce temperature and flame resistant fibers. PBI fibers are resistant to chemicals, do not burn or melt and produce minimal smoke. The fibers accept colors well using basic dyes. PBI fabric is used for flame-retardant and protective apparel, industrial clothing, aircraft upholstery, and insulation.
