Poly-p-phenylene-2, 6-benzobisoxazole or PBO , is a heat resistant, high performance fiber. The rigid molecular chain structure of PBO consists of a benzene-fused oxazole ring structure. PBO fiber is also stated to be almost ten times stronger than steel. It is due to various properties of PBO, such as high tensile strength and creep resistance, that PBO fiber is considered to be the strongest synthetic fiber to date. PBO fibers are difficult to manufacture due to the dry jet wet spinning process. The manufacturing of PBO is expensive and hence, PBO fiber is only manufactured for high-end applications, such as defense and sports goods. Apart from its strength, PBO is also heat resistant, possesses low flammability and is resistant to most organic solvents. However, exposure to strong chemicals, such as strongly acidic and basic solutions, results in loss of strength in case of PBO fibers. However, PBO is comparatively stronger than other synthetic fibers. Request for Brochure @ ...
