It has excellent dielectric, thermal and mechanical properties and it is resistant to fire, water, and biological growth. Nomex is laminated then expanded to form the lightweight core in board honeycomb structural boards. Nomex retains its properties at temperatures up to 370C (700F). It is fire resistant and is used in fire fighters clothing. It is also used for military flight suits and other applications in the space program.
