Kevlar Rope
Kevlar rope is a synthetic fiber rope made from the DuPont Company's product Kevlar, a light but very strong Aramid fiber. Kevlar rope has more strength pound-for-pound than steel. These ropes have low elasticity, high strength, high chemical resistance, and are easy to splice.
The main disadvantage of Kevlar ropes is that they are easily damaged. Synthetic fiber ropes are less tough than steel wire rope and they show the damage they receive quite simply. Kevlar rope damage often tends to look less severe than it actually is so it is frequently used even when it should be retired and does not provide optimal performance.
Kevlar ropes are used in most common wire rope constructions. Some applications of Kevlar rope include oceanographic mooring, mine sweep cables, riser tensioners, moorings on oil rigs, winch lines for utility trucks, helicopter slings, oil containment booms, and the lift lines of cranes.
