Nomex® Fibers

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.

  • DuPont™ Nomex® Prevails in Tough Two Year Testing Programme

    The official opening of RAGTAL (Regionale Atemschutz-Geräte-Träger-Ausbildungsanlage), the Luxembourg Regional Respiratory Equipment Wearers’ Training Facility, heralded the start of a long-term test on fire protective apparel made of DuPont™ Nomex. Two years on and the first results from the test are now available.


  • Time is of the Essence

    Time plays a crucial role in the protection cycle of PPE and so it is important that firefighters consider how their garments behave and interact with the wearer during and after these events to ensure they take the correct course of action and are properly protected.

  • Nomex® for Performance Durability

    Garments made of Nomex® fibre have helped protect firefighters for decades. Continuous exhaustive testing proves that they excel in the long-term retention of their heat and flame protective qualities.

  • Nomex® for Lower Wear-Life Cost

    Today’s firefighters need to be able to optimise budget vs. performance, without compromising on safety. For decades DuPont™ Nomex® fibre has demonstrated lasting protective performance, while helping to minimise repair and maintenance costs.

  • Nomex® for Heat Stress Protection

    Heat stress is a dangerous condition in any situation, but for firefighters it can be especially life threatening. In fact, heat stress is the number-one cause of casualties among firefighters. Nomex® fibre helps reduce heat stress due to its higher air permeability.

  • Nomex® for Extra Seconds of Safety

    Extensive testing shows that Nomex® fibre has remarkably low heat transfer. Under flash fire conditions, it helps provide firefighters valuable extra seconds of safety when they’re needed most.
