Thermal Properties

STARAMID® CG-PBO fiber products have the highest heat resistance among organic fibers, with a thermal decomposition temperature over 650℃ in nitrogen and over 600℃ in air. STARAMID® CG-PBO fibers can be used in high temperature environments for a long time, maintaining high strength retention rate. The products, with limit-oxygen-index over 68%, do not burn in the air and have no melting droplets, so that can be used as a fireproof and flame-retardant material.

Moisture And Heat Resistance Performance

PBO fibers can be affected by moisture and heat aging, where the mechanical

properties of HM type fibers are better than AS type fibers. We recommend storing

and using this product in a dry, non high-temperature environment.

UV Resistance Performance

The lighting environment has a significant adverse effect on the

strength of PBO fibers. We recommend to avoid long-term storage

and use in strong light environments.
