Polyester has the least stretch and best abrasion resistance when compared to nylon and polypropylene. While polyester has a slightly lower strength-to-weight ratio when compared to nylon it is not significant for most applications. Due to its low stretch characteristics polyester cannot absorb shock loads very efficiently. Polyester does not absorb water, which keeps its weight down when wet, has excellent ultraviolet (UV) light resistance, and hold knots well. Popular for extended outdoor uses such as clotheslines, flagpole rope, and boating and camping applications.
