Dyneema® SK60 has the highest level value of the specific strength among commercialized organic strong fibers. A 10mm diameter rope of Dyneema® SK60 can bear up to a 20ton(theoretical value)-weight load.
Dyneema® SK60 has the highest level value of the specific strength and modulus among commercialized organic fibers. Specifically, the brand-new Dyneema® NKS achieves a strength of 40cN/dtex or more.(c.a.4GPa)
Specific Strength vs. Modulus
Dyneema® SK60 is the only super-fiber with a density below 1.0 (the fiber can float on water).
The specific gravity of Dyneema® SK60 is 0.97, which is the lowest value among super fibers and is lighter than water.
Density of Some Fibers
Dyneema® SK60 has an extremely high impact strength. Due to its very high energy absorption characteristics, Dyneema® SK60 is a suitable material for protective applications or sport composites applications.
Dyneema® SK60 exhibits excellent flexibility and excellent abrasion resistance. Easy fabrication offers various textile applications.
Dyneema® has excellent abrasion and fatigue resistance. Due to its ability to be processed easily. (weaving, knitting etc.), this leads to wide applications for industrial use.
Abrasion Resistance and Flex Life
With no degradation due to water absorption, Dyneema® SK60 is the ideal material for ropes or nets used in marine and off-shore applications. Dyneema® SK60 has excellent light stability and chemical resistance in a wide pH range.
Dyneema® shows good light stability due to its chemical and highly crystallized structure. Dyneema® can be used without special covering or coatings.
Good Light Stability
Dyneema® shows excellent chemical stability in a wide pH range, which prompts the application for chemical industries. Because there is no degradation from sea water absorption, Dyneema® is an ideal material for marine and off-shore use.
Excellent Chemical Stability (treat with 23 × 2000 hrs)
Dyneema® has a feature that it expands by lowering the temperature. Dyneema® is an ideal material for cryogenic use that controls the dimension change of composites which is used under the room temperature and extremely low temperture.

- Vibration damping
- Dyneema® has excellent vibration damping characteristics.
- Fundamentally a form of polyethylene, Dyneema® possesses the same chemical properties, making it an outstanding insulator.
- As indicated by its chemical formula -(CH2-CH2)n- Dyneema® is formed from carbon (C) and hydrogen (H). Consequently, even if Dyneema® is burned all that remains is water (H2O) and carbon dioxide (CO2) and no harmful substances are released.
