Nomex® Fibers for Heat- and Flame-Resistant Protection

DuPont™ Nomex® fibers are heat- and flame-resistant, and are used in protective fabrics, garments, electrical paper for insulation, and other high-performance applications to help provide protection to millions of people and processes worldwide.

Nomex® is an inherently flame-resistant, high-temperature resistant fiber that will not melt, drip, or support combustion in air. It is offered in paper, felt, fabric, and fiber forms.

Nomex® brand fiber is used across a diverse range of applications, but it is perhaps best known as a critical component in protective apparel. Today, more than three million firefighters around the world are protected by turnout gear, stationwear and accessories made of Nomex® for its unique combination of flame protection, durability, and comfort. Nomex® is also used in apparel worn by military and police forces; auto racing drivers, pit crew members and track officials; and industrial workers at risk from flash fire and electric arc hazards.

Nomex® fibers are instrumental beyond protective apparel, as well. The mechanical toughness and thermal stability of Nomex® fibers provide high reliability in the most demanding automotive applications such as turbocharger hoses. Industries from asphalt and cement plants to chemical and steel factories use filter media made of Nomex® fiber. Motor, generator, transformer, and other electrical equipment manufacturers have used DuPont™ Nomex® paper, a standard for electrical insulation, for more than 40 years. Honeycomb of Nomex® paper is used for lightweight structural support and helps substantially improve the performance of commercial aircraft.
