PBI LP is a revolutionary new PBI fiber that maximizes flame and break-open protection in light-weight outer shells.
We were able to achieve this by strengthening the bonds between the PBI polymer chains.
That allows us to make much lighter outer shells while increasing flame resistance and break-open protection.
The decomposition temperature of PBI LP fiber is ~1500˚F, making PBI LP outer shells the most protective fabrics available.
MORE FLAME RESISTANCE
Outer shells made with PBI LP offer 30% more flame resistance than traditional PBI fabrics.
The Dynamic Flame Test below is used to demonstrate the time it takes for an outer shell fabric to break down. PBI LP lasts over 40 seconds while any Nomex®/Kevlar® blend lasts only 3-4 seconds.
