PBI vs Nomex/Kevlar - Dynamic Flame Test
A dynamic flame demonstration that compares the thermal resistance of PBI-blended fabrics versus Nomex/Kevlar blends.
With a thermal decomposition temperature of 1300 degrees Fahrenheit, PBI significantly outperforms traditional Nomex/Kevlar blends which break open at much lower temperatures.
This dynamic flame test demonstrates the time it takes for an outer shell fabric to break down. As you can see the Nomex/Kevlar blend breaks down at about five seconds, while the PBI-blended fabric lasts for a full 29 seconds.
By choosing PBI, you’re getting the highest protection available. Consider it firefighter insurance: in worst-case situations, you know you can rely on an outer shell that provides maximum protection that doesn’t break open.
