History Originally called HT-1, Nomex® was first developed in the 1960’s and made commercially available in 1967. FIBER-LINE®’s ability to add value to the already attractive properties of both Kevlar®Para-Aramid & Nomex® Meta-Aramid creates more opportunity in the market place to provide solution driven products to a diverse range of markets. • Because FIBER-LINE® already processes so many dif- ferent types and deniers of both Kevlar® & Nomex®, we have been authorized by DuPont™ to distribute small quantities of these fibers to an ever-growing customer base
