Polypropylene is a general-purpose synthetic rope that is good for outdoor use. It is lightweight, floats and is rot and mildew resistant, making it a good choice for pools and other water activities. It has medium stretch characteristics that allow the rope to stretch slowly. Can be stored wet or dry; store away from direct sunlight for extended life. Hollow core rope does not hold knots well and has limited abrasion resistance. Do not use for overhead lifting. Never exceed the Safe Working Load (SWL).
