Product Details
3 Strands Twisted Polypropylene Rope PP Danline Marine Rope
Floating Rope
1.General Description
QINGDAO JINCHENG MARITIME mooring rope series includes nylon,
polypropylene filament, polypropylene, polypropylene/polyester
blend, polyester and other varieties, which are widely used, with
high strength, low elongation, wear resistance, corrosion
resistance and other advantages, soft and smooth, easy to operate,
and can also be used to make special anti-static ropes. The
products are mainly used in ships, fishing, port loading and
unloading, power construction, oil exploration, sports goods,
national defense research and other fields.
- Inherent Floating Ability: Made from lightweight polypropylene (PP) material, this rope has
a density lower than water, enabling it to float on the surface of
both freshwater and saltwater. Unlike sinking ropes (e.g., nylon),
it avoids submerging and tangling with underwater obstacles like
rocks, 水草 (aquatic plants), or seabed debris—critical for
maintaining visibility and easy retrieval in marine environments.
- 3-Strand Twisted Structure for Balanced Strength & Flexibility: The classic 3-strand twisted design distributes tension evenly
across each strand, delivering reliable tensile strength for light
to medium marine tasks. This structure also keeps the rope flexible
and easy to handle, allowing for quick knot-tying, coiling, and
adjustment—essential for on-deck operations where efficiency
matters.
- Excellent Resistance to Saltwater, Chemicals, and Mildew: PP Danline marine rope is highly resistant to degradation from
saltwater, making it suitable for long-term use in coastal or
offshore settings. It also repels common marine chemicals and
prevents mildew/mold growth, as polypropylene does not absorb
moisture. This resistance ensures the rope retains its structural
integrity and performance, even after prolonged exposure to harsh
marine elements.
- Good Abrasion Resistance for Daily Marine Wear: The twisted 3-strand construction creates a durable outer surface
that withstands friction against boat hulls, docks, metal cleats,
or rocky shorelines. It resists fraying and strand breakage from
repeated contact with hard surfaces, ensuring longevity in high-use
scenarios like daily docking or mooring.
- Lightweight & Low Water Absorption: Compared to heavier marine ropes (e.g., polyester or nylon), this
PP rope is lightweight, reducing user fatigue during handling,
carrying, or deploying. Additionally, its non-absorbent nature
means it does not gain weight from water absorption—even after
prolonged immersion—keeping it easy to manage and preventing
unnecessary strain on equipment like winches or cleats.
- Small Boat Docking & Mooring: Ideal for docking and mooring small recreational vessels (e.g.,
kayaks, canoes, small sailboats, or fishing boats) in marinas,
lakes, or coastal areas. Its floating property ensures the rope
stays visible and accessible, while saltwater resistance and
flexibility make it easy to secure to docks or buoys without
tangling underwater.
- Marking Lines for Marine Areas: Used to mark temporary or permanent marine zones, such as
swimming areas, no-wake zones, fishing boundaries, or underwater
hazards (e.g., reefs, shallow spots). Its floating ability keeps
the line visible on the water surface, and resistance to
mildew/saltwater ensures it remains functional for extended
periods, even in harsh outdoor conditions.
- Fishing Gear & Angling Applications: Suitable for fishing-related tasks, such as tying fishing nets,
securing bait buckets, or creating temporary lines for holding
catch. Its lightweight design avoids weighing down gear, and
resistance to saltwater prevents corrosion—making it a reliable
choice for both freshwater and saltwater fishing trips.
- Water Sports & Recreational Activities: Perfect for water-based recreational use, including towing
inflatable toys (e.g., water tubes, rafts), setting up temporary
swimming ropes, or marking paths for kayaking/canoeing tours. Its
floating nature ensures safety (users can easily spot and avoid the
rope), and flexibility allows for quick setup and adjustment.
- Light-Duty Marine Equipment Securement: Used to secure light on-deck equipment, such as fenders, life
jackets, small coolers, or paddle storage. Its tensile strength
handles the weight of light gear, and low water absorption means it
won’t become heavy or cumbersome—even after exposure to rain or
splashes. It keeps equipment organized and secure during short
boating trips.
