DuPont Nomex is a high-performance brand of flame-resistant meta-aramid fibers and paper products developed for critical thermal protection and electrical insulation applications. As a core component of the Aramids business acquired by Arclin from DuPont for $1.8 billion in 2026, Nomex provides inherent heat and flame resistance that does not wash out or wear away, making it essential for firefighter turnout gear, military flight suits, and industrial protective apparel. Beyond textiles, the material is utilized in honeycomb structures for aerospace weight reduction and as specialized paper for insulation in electric motors and transformers.
