Alkex® Para-Aramid Physical Properties Guide
Para-Aramid fibers such as Alkex® & Kevlar®, offer a multitude of properties that make them an excellent choice for various applications. Their exceptional strength-to-weight ratio and high break strength provides high tensile strength and modulus, making them ideal for applications requiring robust and durable materials. Para-aramid fibers are great solution for applications where the fiber will be under constant load, taking advantage of low elongation and creep properties.
Alkex® 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 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
Alkex® Para-Aramid Performance Highlights
- High strength: Exceptional tensile properties with strength greater than steel on a weight-to-weight basis
- Durability: Excellent resistance to impact, abrasion, and puncture.
- Lightweight: Superior strength-to-weight ratio for high-performance applications.
- Thermal resistance: Maintains integrity and mechanical properties at elevated temperatures.
- Chemical resistance: Good stability in many chemical environments (see limitations above).
- Flame resistance: Offers strong flame protection and self-extinguishing characteristics.
- Dimensional stability: Maintains structure under stress for long-term performance.
- Low Electrical Conductivity: High dielectric strength, suitable for electrical insulation applications.
