where it is saturated with a phenolic resin. Honeycomb structures such as these, as well as mylar-Nomex laminates are used extensively in aircraft construction. Both the firefighting and vehicle racing industries use Nomex to create clothing and equipment that can withstand intense heat. All aramids are heat and flame resistant but Kevlar, having a para orientation, can be molecularly aligned and gives high strength. Meta aramid cannot align during filament formation and has poor strength. Nomex fiber is made in the USA and in Spain (Asturias).

Nomex has also been used for its unique acoustic qualities, the first time being used in Troy, NY at Rensselaer Polytechnic Institute's Experimental Media and Performing Arts Center EMPAC's main concert hall. Nomex reflects high-frequency sound, and increases mid- and low-level frequency sound. According to RPI President Shirley Ann Jackson, EMPAC is the first venue in the world to use Nomex for acoustic reasons.
