polybenzimidazole
Sign in to saveAlso known as PBI, poly[(1,5-dihydrobenzo[1,2-d:4,5-d′]diimidazole-2,6-diyl)-1,4-phenylene]
Polybenzimidazole (PBI, short for 'poly[2,2’-(m-phenylen)-5,5’-bisbenzimidazole]') fiber is a synthetic fiber with a very high decomposition temperature. It does not exhibit a melting point, does not readily ignite, and has exceptional thermal and chemical stability. It was first discovered in 1961, by American polymer chemist Carl Shipp Marvel in the pursuit of new materials with superior stability, retention of stiffness, and toughness at elevated temperature. Due to its high stability, polybenzimidazole is used to fabricate high-performance protective apparel such as firefighter's gear, ast

Polybenzimidazole (PBI, short for 'poly[2,2’-(m-phenylen)-5,5’-bisbenzimidazole]') fiber is a synthetic fiber with a very high decomposition temperature. It does not exhibit a melting point, does not readily ignite, and has exceptional thermal and chemical stability. It was first discovered in 1961, by American polymer chemist Carl Shipp Marvel in the pursuit of new materials with superior stability, retention of stiffness, and toughness at elevated temperature. Due to its high stability, polybenzimidazole is used to fabricate high-performance protective apparel such as firefighter's gear, astronaut space suits, high temperature protective gloves, welders’ apparel and aircraft wall fabrics. Polybenzimidazole has been applied as a membrane in fuel cells.
