What is Nomex®?

DuPontTM Nomex® is a heat- and flame-resistant meta-aramid fiber used across a diverse range of applications – perhaps most commonly known as a key component in fabrics utilised to create protective apparel. Due to its unique combination of heat, flame and electric arc protection, durability and comfort, the Nomex® brand is trusted amongst those working in dangerous conditions such as firefighters; military pilots and combat vehicle crew; auto racing drivers, pit crew and track officials; and industrial workers at risk from flash fire and electric arc hazards.

Inherently flame resistant, Nomex® offers supreme strength and heat performance versus many other products on the market. It doesn’t melt, drip or support combustion in the air. A key factor in the protection provided by Nomex® is its ability to carbonize and thicken when exposed to intense heat. This typical reaction increases the protective barrier between the heat source and the wearer’s skin and minimizes burn injury. As the protection is engineered into the molecular structure of the Nomex® fiber (as opposed to chemical treatment), the heat and flame resistance will last the lifetime of the garment – the protection cannot be washed out or worn away.

Nomex®: A synthetic fiber for coverall, gloves, suits & more

Nomex® PPE garments are created using Nomex®-based fabric, stitched together with Nomex® thread, providing optimal protection for the wearer against multiple hazards. This includes items such as: coveralls, protective gloves, suits (multi-layer jackets and trousers), balaclavas, hoods, trousers, tops and underwear (non-melting).
