Flame Resistant Nomex® Brand Fiber — Trusted Thermal Protection

Mass transit systems, wind energy, transformers, filtration — not all industries that rely on the inherent protection of Nomex® are life-saving ones.

But they’re still essential to our way of life.

It started with a flight suit. And 40 years later, DuPont™ Nomex® fiber is still a first choice for workers who rely on its inherently flame resistant properties to help keep them safe from the everyday hazards they face.

We go beyond basic test methods to help ensure that workers stay protected. Our Thermo-Man® testing lab puts garments made of Nomex® fiber through a rigorous series of fire scenarios that simulate real-life situations — making it one of the most advanced thermal burn injury evaluation devices in the world. Our dedication to safety has made Nomex® the go-to fabric for manufacturers who make products for protecting firefighters, Air Force pilots, and industrial workers.

And we’re not stopping there. We’re constantly working with mills and garment manufacturers to help them make products made from flame resistant Nomex® brand fiber stronger, more durable and safer. We’ve expanded its uses and applications to include transformers, motors, and generators. Our commitment to innovation is the same as it’s been for the past four decades. Our mission is to: help people and materials perform better — even in extreme conditions.
