DuPont Nomex vs Meta-aramid

Home / Blog / DuPont Nomex vs Meta-aramid

DuPont’s Nomex is a brand of meta-aramid fiber, which is known for its excellent thermal, chemical, and flame-resistant properties. Here’s a comparison between Nomex and generic meta-aramid fibers:

DuPont Nomex:

•  Is a specific brand of meta-aramid developed by DuPont

•  Offers inherent flame resistance that cannot be washed or worn away.

•  Its fibers thicken and carbonize when exposed to intense heat, absorbing energy in the process.

•  Does not melt, drip, or support combustion

•  Used in a wide range of applications, including firefighting gear, industrial workwear, military uniforms, and race car driver suits

Meta-aramid in General:

•  Refers to a category of aramid fibers with a meta-linkage of aromatic groups.

•  Is flexible and higher in elongation, making it suitable for textile yarns in fabrics.

 DuPont NomexMeta-aramid
CompositionNomex is a meta-aramid fiber made from poly-meta-phenylene isophthalamide.Meta-aramid fibers have a similar molecular structure to Nomex but may be produced by different manufacturers.
PropertiesNomex fibers are known for their exceptional thermal stability, flame resistance, and resistance to chemicals. They do not melt, drip, or support combustion easily, making them ideal for protective clothing in high-temperature and hazardous environments.Meta-aramid fibers in general share many properties with Nomex, including flame resistance, thermal stability, and chemical resistance. They are also known for their strength, durability, and resistance to abrasion.
Applications Nomex fibers are commonly used in flame-resistant clothing for firefighters, industrial workers, military personnel, and other applications requiring protection from heat and flames.Meta-aramid fibers, including those produced by other manufacturers besides DuPont, are used in a wide range of applications such as protective apparel, insulation for electrical equipment, automotive components, aerospace materials, and industrial fabrics.

While both DuPont Nomex and generic meta-aramids share similar chemical structures and properties, Nomex is a trademarked product that comes with the quality assurance and technical support of DuPont. It’s designed for specific high-performance applications where its unique properties are essential.
