Nomex is a registered trademark for flame-resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967.

Properties

Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is the premier example of a meta variant of the aramids (Kevlar is a para aramid). Unlike Kevlar, Nomex cannot align during filament formation and has poorer strength. However, it has excellent thermal, chemical, and radiation resistance for a polymer material.

Production

The polymer is produced by condensation reaction from the monomers m-phenylenediamine and isophthaloyl chloride.

It is sold in both fiber and sheet forms and is used as a fabric wherever resistance from heat and flame is required. Nomex sheet is actually a calendered 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. Nomex fiber is made in the USA and in Spain(Asturias).

Nem (Vietnamese: món nem) is a Vietnamese sausage. Depending on the locality, nem may refer to a rolled sausage in rice paper called nem cuon or nem ran (fresh and fried rolls, respectively), barbecued sausage called nem nướng or cured sausage called nem chua.

Types

Banh Trang Rolls

Nem used to refer to banh trang rolls (fresh and fried) is more commonly used in Northern Vietnam.

Nemíž is a village in Benešov District in the Central Bohemian Region of the Czech Republic, from 2009 part of municipality Tehov.
