Zylon PBO Rigid Rod Polymer Fibers

Material Time to ignition (Seconds) Peak heat release rate Light extinction in Smoke column Residue (%) 

The chemical structure of PBO is similar to that of poly 2,6-diimidazo[4,5-b 4, 5 -e]p yridinylene-l,4-(2,5-dihydroxy) phenylene) (PIPD), the new M5 fiber. PBO has great thermal stability and does not exhibit softening behavior prior to thermal
