<p>Cobalt Blue Polypropylene Rope is the strongest synthetic rope in its class thanks to extremely tight tolerances in manufacturing from fiber extrusion to the finished rope. The result is a rope of very high quality and consistency.</p> <div class="product_description_list"> <ul> <li>Approximately 40% stronger than standard polypropylene ropes</li> <li>18% elongation</li> <li>Excellent UV protection</li> <li>Superior abrasion resistance</li> <li>No loss of strength when wet</li> <li>Can be stored wet</li> <li>Resists rot and mildew</li> </ul> </div> <p>One issue with polypropylene to consider is that UV light slowly breaks down the fibers of the rope. Over time, if left outside, this rope will take on a rough and fuzzy appearance. This is perfectly normal, but makes the rope pretty scratchy.</p>
