Chopped Dyneema®

Dyneema® is an ultra-high molecular weight polyethylene (UHMWPE) fiber recognized globally for its exceptional strength-to-weight ratio and outstanding abrasion resistance. Pound for pound, Dyneema® is significantly stronger than steel, while remaining extremely lightweight and flexible. Its low density, high impact resistance, and excellent fatigue performance make it a preferred material in advanced composite and energy-absorbing systems.

Rocket-Fibers’ chopped Dyneema® fibers are precision cut using advanced processing technology to ensure consistent fiber length, clean cut geometry, and minimal fibrillation. This controlled cutting process delivers uniform dispersion and repeatable performance in molded parts, composite systems, and engineered materials.

Our precision cut Dyneema® fibers are offered in multiple standard lengths and quantities to support applications ranging from R&D prototyping to commercial production. Custom cut lengths, tailored packaging, and batch-level Certificate of Analysis (COA) documentation are available upon request to meet your specific quality and traceability requirements.

    Dyneema® Resistance Guide

    UHMWPE fibers like Spectra® or Dyneema® offer high resistance to corrosive substances, such as most acids, alkalis, and organic solvents, making them valuable in industrial settings where chemical exposure is commonplace. However, UHMWPE fibers are not without their shortcomings. They exhibit limited thermal stability, which reduces their performance and longevity at elevated temperatures. While their melting point is approximately 135-147°C, they begin to lose their properties around 100°C. Moreover, UHMWPE fibers possess low flame resistance. In a fire or high-heat scenario, they readily melt and burn.

    This fiber exhibits poor flame resistance and will melt at 135°C. It is not advisable to use in any application where an open flame is present.

    This fiber exhibits poor heat resistance and will melt at 135°C. It is not advisable to use in any application where high heat is present.

    Acid: Highly resistant to most acids, maintaining their mechanical properties
    Alkali: Withstand exposure to most alkalis with minimal degradation
    Organic Solvent: Generally compatible with a variety of organic solvents

    Continuous Operating Temperature Range (°C): -150 to 70
    Short Term Exposure (°C): 100
    Melting Temp (°C):144 - 152
