Nomex® LS

DuPont™ Nomex® LS

DuPont™ Nomex® LS is a technology platform offering new properties such as light weight and strength to the inherent flame retardant properties of Nomex® fibres.

In addition, LS technology is appropriate for blends with wool.

Fibre composition

93% 1.7 decitex DuPont™ Nomex® meta-aramid
5% DuPont™ Kevlar® para-aramid
2% antistatic fibre


N324 and N329 are yarns made of the Nomex® LS platform which helps provide superior aesthetics and mechanical properties to the fabrics made thereof.

Mainly used for applications where lightweight solutions are required, such as police uniforms, pilot suits; chemical, biological, radiological and nuclear protection outer fabrics, ballistic vest covers and Explosive Ordnance Disposal (EOD) suits and police officer uniforms.

Antistatic properties

Nomex® LS has antistatic properties – fabric is tested in accordance with EN 1149-3 and addresses the electrostatic protection requirements of EN 1149-5 for protective clothing.


  • Nomex® & the Thermo-Man® Test

    DuPont™ Thermo-Man® is a life-size mannequin equipped with 122 heat sensors dressed in test garments and exposed to a flash fire with temperatures rising up to 1,000°C.

  • 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.
