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.
