What is PBI?
PBI (Polybenzimidazole fiber) is a manufactured fiber in which the fiber-forming substance is a long chain aromatic polymer having recurrent imadazole groups as an intricate part of the polymer chain. It can be used in its raw state or blended with other fibers (Kevlar®/PBI). PBI has high moisture regain, low modulus, and comfort properties similar to cotton. These properties and those below make PBI, and blends of PBI, very useful in safety and protective applications.
