What is Nomex®?

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.

Arc flash

The molecular structure of Nomex^® that prevents heat from passing through it also prevents electricity from flowing through it when exposed to electrical arc.

Electrical insulation

Because Nomex^® is a poor conductor of electricity, it makes for a remarkable insulator when used in paper sheets and boards.

Chemical resistance

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.
