    Kevlar® Resistance Guide

    Para-aramid fibers, such as Kevlar®, 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, Kevlar® fibers demonstrate good chemical resistance, enabling them to withstand exposure to acids, alkalis, and many organic solvents without significant degradation. 

    This fiber will degrade with prolonged UV light exposure. These fibers will brown and weaken over time.  Please keep this fiber stored away in a dark room and in the UV protective bag the fiber was shipped in.

    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): -40 to 170
    Short Term Exposure (°C): 420
    Degradation Temperature (°C): 480
