Nomex® IIIA

DuPont™ Nomex® IIIA

DuPont™ Nomex® IIIA: this innovative solution expands to form a stable and inert barrier between the fire and skin, which gives wearers the valuable seconds they need to help them escape from the hazard.

Fibre composition

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

Applications

Mainly used for blended solutions containing viscose FR and/or other fibre chemistries, resulting in a balanced composite blend meeting the rigors of the application. Woven or knitted fabrics made for single or multilayer garments, including underwear and shirts.

Antistatic properties

DuPont™ Nomex® IIIA  has antistatic properties. Fabrics made of Nomex® fibre are tested in accordance with EN 1149-3 and fulfill the electrostatic protection requirements of EN 1149-5 for protective clothing.

More protection

Nomex® IIIA helps protect against low volume chemical splash and mist (EN 13034) if treated with fluorocarbon finish. Additional properties can be achieved by combining fabrics made of DuPont™ Nomex® fibres with other materials to provide protection against environmental hazards of rain (EN 343 and EN 14360), cold and cool environment (EN 342 and EN 14058), and against low voltage electrical current hazard (EN 50286).

Protection and norms

Thermal protection against heat and flame (EN531, ISO/FDIS 11612, EN 469) and electrical arc (IEC 61482-2/CDV).

Colour availability

Can be supplied pigmented for best light fastness or piece-dyed.

INFORMATION & IDEAS

  • 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.
