MultiMix F doubler

The multimix F doubler is the newly modified double blade rope whose structure is made to enhance its maximum strength.

Since this rope is a compound of polyester and polypropylene, it has not only the high resistance of water, weather and abrasion, but has excellent workability due to its lightweight and floating characteristics.


  1. Material
    • Inner layer: polypropylene
    • Outer layer: compound of polypropylene and polyester
  2.  Structure: double blade
  3. Specific gravity: 0.98
  4. Degree of elongation: about 20%


Repeating fatigue characteristic

Comparing the strength of retention, after periodic loading / usage of the rope, by repeating the process.

Test condition
