DuPont™ Nomex® and other aramid polymers are related to nylon but have aromatic backbones. As a meta-aramid, Nomex cannot align during filament formation and has poorer strength than para-aramids, like Kevlar. But Nomex provides solid flame and heat resistance nonetheless.
Nomex has a wide variety of applications in many industries where heat and flame resistance are important attributes. Used extensively in electrical insulation and aircraft construction, Nomex has provides the right combination of factors to be an excellent candidate for a fiber used in protective fabrics.
Wildland firefighters wear Nomex shirts and trousers for flame and heat protection as do racecar drivers and military pilots. TenCate Protective Fabrics is the world’s largest manufacturer of Nomex fabrics and uses more Nomex fiber than any other company on the planet.
