DuPont launches 'Nomex XF' solution for aerospace industry

Nomex XF is a novel 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 also can help prevent flame propagation so that aircraft insulation will not spread fire.

“DuPont has a long history of delivering innovations to support the aerospace industry,” said Marc Doyle, president, DuPont Protection Technologies. 

“DuPont Kevlar and Nomex fiber have been successfully used by the aerospace industry for more than 40 years and Nomex XF is the latest step in our commitment to protecting commercial aircraft and their passengers.  This novel material addresses an important industry need and shows how a collaborative effort can help bring innovative solutions to the market.”

Developed in response to customer needs, Nomex XF was designed for use in commercial aircraft and can be readily incorporated into designs compliant with Federal Aviation Regulations (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 can be incorporated into thermal acoustic insulation constructions; it has no flame penetration after 10 minutes exposure, more than doubling the burnthrough time requirements of FAR 25.856(b).
