Nomex (styled NOMEX) is a registered trademark for flame resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967.
Many synthetic materials cascaded from DuPont research, forming the basis for many global businesses and products including household names such as Teflon® fluoropolymer resins and SilverStone® certified non-stick finishes, Stainmaster® flooring systems, Kevlar® brand fiber, Nomex® brand fiber and paper, Lycra® spandex fiber, Sontara® spun-laced fabric, Mylar® polyester film, Tyvek® spunbonded olefin, Cordura® nylon fiber, and Corian® solid surface material.
2007 marks the 40th anniversary of the commercialization of DuPont™ Nomex®, a revolutionary, heat and flame resistant fiber that when used in protective fabrics, garments, insulation and other high-performance applications help provide protection to millions of people and processes worldwide.
Nomex is an inherently flame-resistant, high-temperature fiber that will not melt, drip or support combustion in air. It also delivers outstanding resistance to a broad range of chemicals. You can find it as a paper, felt, fabric and in fiber forms.
Nomex brand fiber is used in range of applications, but it is perhaps best known as a critical component in protective apparel. Today, almost all firefighters around the world are protected by Nomex for its unique combination of flame protection, durability and mobility. Nomex is also used by military pilots and combat vehicle crew; auto racing drivers, pit crew members and track officials.
Nomex goes beyond protective apparel, though. Motor, generator, transformer and other electrical equipment manufacturers have counted on DuPont Nomex, the standard for electrical insulation, for more than 40 years.
Honeycomb of Nomex paper is used for lightweight structural support and helps substantially improve the performance of most commercial aircraft.
