CarbonX fabrics are constructed utilizing oxidized polyacrylonitrile fibers (OPF). At 250°F, OPF is the only fiber to still possess 100% of its original strength, and after ten minutes of exposure at temperatures of 500°F, OPF outperforms the competition and retains an astonishing 40% of its strength. CarbonX fabrics are unsurpassed. CarbonX fabrics will not ignite, burn, melt, shrink or significantly decompose when exposed to intense flame, molten metal, or arc flash. When exposed to direct flame and temperatures of more than 2000°F, CarbonX is the only non-flammable fabric that retains strength and flexibility and maintains its persistent barrier. This level of performance buys crucial time for individuals in these hazards and without question can mean the difference between life and death.
