It was created by the same company in 1967. It has properties similar to Kevlar but it is characterized more with its resistance to heat. Which explains its popularity in clothing for firefighters. Nomex has proven protection against intense heat and flames, such as incendiary bombs, explosive ordnance, fires and electric arcs.
No decomposition or melting is observed up to 600 –800 °C. It exhibits an excellent performance in uses where protection against heat and electricity is required. Dupont's Nomex is an example. The second class aramids are Kevlar, a para aramid fiber introduced by DuPont in the early 1970s.

· Fabrics classified as fireproof include Nomex, Kevlar, and Modacrylic. Technically, the only 100% fireproof fabric ever designed contained asbestos. For obvious safety reasons, no one makes this material anymore! Instead, scientists have developed other products like Nomex that can catch on fire, but only at insanely high heat. ...
· Kevlar aerogel fibers which inherit the aerogel's brilliant properties of low density, high porosity and large surface area are promising candidates for thermal insulation applications in textiles. To enhance the mechanical strength of Kevlar aerogel fibers, an extra Nomex shell was introduced by a simple coaxial-wet-spinning approach.
· Nomex is the trade name of meta aramid fiber. Aromatic polyamide resins which have been developed by Du Pont include the zigzag-linked meta-type is called Nomex. In the meta-aramid fiber Nomex, tensile fatigue occurs in a similar form to that in Nylon. Nomex is made in fiber and fibrid (very short particles) forms.

· Kevlar and Nomex are high-performance polymers which have wide varieties of applications in daily life. Recently, they have been proposed to be biocidal materials when reacted with household bleach (sodium hypochlorite solution) because they contain amide moieties which can be chlorinated to generate biocidal N-halamine functional groups.

· A primary limitation is that Kevlar disintegrates at about 900 ºF. Nomex. Nomex (aka poly (m-phenylenediamine isophthalamide)) came on the market in 1967 and is a close relation of Kevlar. Compare the Kevlar and Nomex molecules shown below. They’re very similar, but the positions of some of the atoms in Nomex make it, well, a little kinky.
