    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.

    This fiber will absorb atmospheric moisture up to 5-7% in weight. This fiber should be stored in a cool, dry room with low humidity. A desiccant bag was included with this fiber to prevent regain during transit and short-term storage at your facility.

    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): 300
