Size for size, Dyneema® SK75 has approximately one twelfth of the weight of steel wire rope - handling a rope with a breaking strength of several hundred tons is no obstacle for one man. G NEUTRAL BUOYANCY
Specific gravity: 0.97, i.e. floats. G EXCELLENT TENSION FATIGUE
Tension fatigue (OCIMF) of 8 strand ropes. Residual strength after 1,000 cycles repeated at 50%, 60%, 70% and 80% of breaking load. Rope material Residual Strength Dyneema® (at 95% Breaking Load) Aramid Polyester Steel (laid) Polyamide Polypropylene

G BENDING FATIGUE
We recommend a minimum sheave/rope diameter ratio greater than 10:1. This will help ensure a very long service life which, at normal working loads, will be at least as long as that of wire rope.
