DuPont™ Nomex® is a registered trademark for flame-resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967. Uses for staple, yarn, and spunlaced products include apparel fabrics to protect against flash fire and electric arc exposure; firefighter garments; fabrics and spun yarns for filtration applications; insulation in fire resistant thermal protective apparel; rubber reinforcement; and in transportation textiles such as aircraft carpeting. Unlike flame-retardant treated (FRT) materials, NOMEX® brand fibers are inherently flame resistant(FR): the flame resistance is an inherent property of the polymer chemistry. It will not diminish during the life of the fiber. The fiber’s low stiffness and high elongation give it textile-like characteristics which allow processing on conventional textile equipment. Since its introduction, the product lines of NOMEX® have been augmented to include a variety of natural and colored fibers and blends, each with unique properties designed to meet specific end-use requirements.
