Nomex® Resistance Guide
Nomex® exhibits 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 like Nomex® 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): 350
Degradation Temperature (°C): 427
