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


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.
