Nomex® Meta-Aramid: Heat & Flame Resistant

Key Features of Nomex® Meta-Aramid:

  • Excellent heat & flame resistance 
  • High chemical resistance
  • Low thermal shrinkage
  • Self-extinguishing flame retardant properties
  • Soft-hand yields good textile properties

Originally called HT-1, Nomex® was first developed in the 1960’s and made commercially available in 1967 by DuPont™.  It was first used as fabric for race-car driver suits.

Similar to Kevlar®, Nomex® is an aromatic polyamide.  The “Meta” linkage position of the aromatic groups differs from that of Para-Aramids.  The chemical bonds are zig-zag in configuration, resulting in a lower tensile and modulus fiber compared to Kevlar®. 

Nomex® is flexible and higher in elongation however, making it an ideal textile yarn for fabrics.
