Zylon® PBO
High Strength & Flame Resistance
History
PBO was first developed in the 1980’s and is extremely strong and flame resistant. It is also the first organic fiber whose cross-sectional strength outperforms both steel and carbon fiber.
Composition
Zylon® PBO is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet-spinning process.
