Poly-p-phenylene benzobisthiazole Polybenzoxazole (PBO)

Polybenzoxazole (PBO), Poly-p-phenylene benzobisthiazole

Polybenzoxazole (PBO) is a high-performance, heat-resistant fiber with a benzene-fused oxazole ring structure. The fiber is almost twice as strong as aramid fibers (Kevlar, Nomex) and about 10 times stronger than steel making it the strongest manmade organic fiber. It also has a 100°C higher decomposition temperature than aramid and exhibits very little creep under stress making it suitable for high continuous loads.
