Our Heavy-Duty Floating Polypropylene Mooring Rope is designed for demanding marine applications, offering excellent strength, buoyancy and durability for securing boats, barges, ships and larger vessels.
Manufactured from 100% High Tenacity Polypropylene Fibre, this rope features a 24 strand braided outer cover and 12 strand inner core, providing a strong, flexible double braid construction.
Unlike polyester and nylon ropes, polypropylene has a specific gravity below that of water, allowing the rope to float on the surface. This makes it particularly useful for mooring operations, dockside handling and marine applications where floating rope is preferred.
Available in 16mm, 18mm, 26mm and 34mm diameters, with unspliced breaking loads up to 15,250kg (15.25 tonnes).
