Twice as strong as Manila Rope, Polyester is about as strong as Nylon. It retains full strength even when wet, a major characteristic that makes Polyester particularly suitable for holding ships at dockside. While it is slightly resistant to some alkalis, it is strongly resistant to acids. Furthermore, it is not susceptible to deterioration caused by rot, mildew, or moisture. Its specific gravity is 1.36 and its abrasion resistance is approximately the same as that of Manila Rope. Polyester is a rope for varied uses. Good for mooring, rigging, and industrial plant use, it is used as fishnet and bolt rope, rope sling, and alongside towing hawser. Ropes can be manufactured to conform to US, British, Canadian, and Australian specifications.
