Para-Aramid Resistance Guide
Para-aramid fibers, such as Alkex® & 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, para-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 exposure.
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 300
Short Term Exposure (°C): 420
Degradation Temperature (°C): 480
Suggested Applications
- Aerospace & Mlitary Sewing Threads
- Fire and Flame Safety
- Industrial Safety Gear
- Medical Textiles
