Nylon/nylon blend is the strongest of all ropes. When stretched has a "memory" for returning to its original length. For this reason it is best for absorbing shock loads as is the case when lifting or towing. Nylon/nylon blend lasts four to five times longer than natural fibers because it has very good abrasion resistance and is not damaged by oil or most chemicals. Nylon/nylon blend has good resistance to ultraviolet deterioration from sunlight (UV stability).
