Nomex is a registered trademark for flame resistant meta-aramid Material developed the early 1960s by DuPont and first marketed in 1967. It can be considered an aromatic nylon, the meta variant of the para-aramid Kevlar. It is sold both fiber and sheet forms and is used as a fabric wherever resistance from heat and flame is required. Nomex sheet is actually a calendared paper and made in a similar fashion. Nomex Type 410 paper is the original and one of the larger grade types made, mostly for electrical insulation purposes. Both the firefighting and vehicle racing industries use Nomex to create clothing and equipment that can withstand intense heat.
