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.

Nomex® Meta-Aramid Bare Fiber Performance
Chemical Resistance to Acid: Strength loss in H2SO4 below acid dew point.
Chemical Resistance to Alkali: Good at room temperature but degraded by strong alkalis at high temp.
