Chopped Para-Aramid
Para-aramid fibers are engineered for exceptional tensile strength, impact resistance, and thermal stability. Known for their high modulus and outstanding energy absorption, para-aramid fibers are widely used in advanced composite systems, ballistic structures, and high-performance industrial components.
Rocket-Fibers’ chopped para-aramid fibers are precision cut using advanced processing technology to ensure consistent fiber length, clean edges, and uniform dispersion within resin systems. This controlled cutting process supports reliable mechanical performance and repeatable results in both thermoset and thermoplastic composite applications.
Our precision cut para-aramid fibers are available in multiple standard lengths and production quantities to support applications ranging from R&D development to commercial-scale manufacturing. Custom cut lengths, tailored packaging, and batch-level Certificate of Analysis (COA) documentation with full lot traceability are available upon request.

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
