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.
