Nomex® Meta-Aramid Physical Properties
While not known for their strength like Kevlar®, Nomex® fibers offer a unique set of properties that make it desirable for a myriad of products and applications. Often times, Nomex® fibers are used in combination with higher strength fibers to help enhance flame and thermal resistance.
Nomex® Meta-Aramid Resistance Guide
Meta-aramid fibers, such as Nomex®, exhibit excellent resistance to high temperatures, maintaining their mechanical properties even at elevated temperatures. This heat resistance makes them suitable for applications in thermal insulation and protective clothing. Additionally, meta-aramid fibers demonstrate good chemical resistance, enabling them to withstand short-term exposure to acids, alkalis, and many organic solvents without significant degradation. Not advised for long-term chemical exposure.
Acid: Prolonged exposure to concentrated strong acids will cause degradation
Alkali: Degrades with prolonged exposure to Sodium Hypochlorite
Organic Solvent: Moderate degradation in Carbon Tetrachloride and Ethylene Glycol
Continuous Operating Temperature Range (°C): -196 to 204
Short Term Exposure (°C): 370
Degradation Temperature (°C): 300

Nomex® Meta-Aramid Performance Properties
Heat Resistance: Nomex®-Meta Aramid fiber exhibits excellent heat resistance, retaining its structural integrity and performance at temperatures up to 370°C.
Flame Resistance: This fiber is inherently flame resistant, meaning it does not melt, drip, or support combustion in the air, ensuring protection in high-temperature environments.
Good Chemical Resistance: Nomex® fibers have good short-term resistance to many chemicals, including acids and alkalis, making them suitable for use in chemically harsh environments.
Radiation Resistance: Nomex demonstrates strong resistance to beta and gamma radiation as well as x-rays.
Dimensional Stability: The fiber maintains its shape and size even under extreme temperature variations, providing reliable performance and durability.
High Dielectric Strength: With high dielectric strength, Nomex® is an excellent insulator, making it ideal for electrical and electronic applications where insulation integrity is critical.
Good Hand/Soft Textile Feel: Despite its robust protective qualities, Nomex® offers a good hand and a soft textile feel, ensuring comfort for wearers in protective apparel.
Durability: Nomex® fibers are highly durable, offering long-lasting performance and resistance to wear and tear, making them suitable for demanding applications.
Low Thermal Shrinkage: The fiber exhibits low thermal shrinkage, maintaining its dimensions and structural properties even after exposure to high temperatures, which is essential for maintaining fit and performance in protective clothing.
