Which statement accurately describes polyester rope characteristics?

• A. Low elongation characteristics
• B. High water absorption
• C. Floats well
• D. No UV resistance

Answer: (A)

Low elongation under load is a defining property of polyester rope. Polyester fibers have a relatively high modulus, so they stretch minimally when weighted, providing predictable length and less shock loading—ideal for static rope work, rigging, and rescue where you need reliable length and control. In practical terms, polyester rope will hold its length more consistently under load compared to more stretchable fibers, making it a stable choice for precise maneuvers. It also resists moisture and UV exposure well, so it dries quickly and resists sun degradation, helping maintain strength over time. It does not float well because its density is greater than water, so it tends to sink rather than stay buoyant. Its moisture absorption is relatively low, not high. The combination of low elongation with good environmental resistance is what makes that statement the best description of polyester rope characteristics.
