Oliveira Libra PA

Oliveira Polyester ropes are used all over the world for towing springs, buoy moorings, capstan hauling, ROV & submersible lift ropes, supply boat mooring and tank mooring. The usage of high tenacity multifilament polyester yarns in our ropes ensures outstanding wet and dry strength and durability against abrasion and fatigue.

Polyester ropes do not absorb water, so they neither harden nor lose strength when wet. These ropes are very easy to splice and have an excellent ultraviolet resistance due to a special treatment of the polyester yarns. These ropes remain flexible and do not become brittle at temperatures of minus 40ºC.
