Polyester is differentiated from the other synthetic rope types by its low stretch characteristics, excellent abrasion resistance, and only slightly lower strength-to-weight ratio when compared to Nylon. Due to its low stretch characteristics, Polyester cannot absorb shock loads very efficiently. It will not absorb water which creates a lightweight material when used outdoors around water applications or during rain. It also has excellent ultraviolet (UV) light resistance, so it is popular for extended outdoor uses, like clotheslines, flagpole rope and boating.
