DuPont™ Nomex® is a heat- and flame-resistant meta-aramid fibre 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.
Heat & flame protection
When Nomex® is exposed to intense heat, its fibers thicken and carbonize—absorbing heat energy in the process. Additionally, Nomex® fibers won’t melt, drip or support combustion.
The molecular structure of Nomex® that prevents heat from passing through it also prevents electricity from flowing through it when exposed to electrical arc.
Because Nomex® is a poor conductor of electricity, it makes for a remarkable insulator when used in paper sheets and boards.
Nomex® fiber is highly resistant to most common acids and alkalis, fluorocarbon refrigerants, transformer oil and silicon.
What are other uses of Nomex®?
The application of Nomex® is by no means limited to PPE. DuPont offers a complete portfolio of high-performance insulation solutions engineered for excellent performance and reliability. The DuPont line of Nomex® electrical insulation products includes papers and pressboards.
Nomex® honeycomb is a composite core material made Nomex® aramid fiber paper. It is widely used for numerous engineering and scientific applications across aerospace, construction, military, marine, sports, and automotive industries, due to its heat resistant properties, lightweight strength and durability, make it an ideal material widely used.
