Nomex® XF flame barrier

DuPont introduces Nomex® XF High Temperature Flame Barrier, a unique solution for your flame barrier applications

Nomex® XF is a unique material that helps protect aluminum fuselage aircraft by providing a robust, durable and lightweight flame barrier that can help prevent outside fire from penetrating an aircraft cabin, allowing passengers additional time to escape such a hazard. It can also help prevent flame propagation so that aircraft insulation will not spread fire.

Developed in response to customer needs, Nomex® XF was designed for use in commercial aircraft and can be readily incorporated into designs compliant with FAR 25.853 and 25.856. It is intended for use in applications that require flame resistance up to 1,100 degrees Celsius (2,000 degrees Fahrenheit). The Nomex® XF flame barrier offers flexible, thin  and very lightweight protection and Nomex® XF can be incorporated into Thermal Acoustic Insulation applications; it has no flame penetration after 10 minutes exposure more than doubling the burn through time requirements of FAR25.856(b).
