Product Description
Polyester/Polypropylene Double Braided Rope
Market Application Scope
1. Maritime Operations
- Ship Mooring: Ideal for large cargo ships, cruise liners, and offshore platforms. Its balanced density (0.975 g/cm³) ensures it stays afloat for easy deployment, while high UV resistance prevents fiber degradation under intense marine sunlight. For example, in tropical ports with year - round strong UV, it maintains strength for long - term dockside use.
- Towing Operations: Used to tow disabled vessels or offshore equipment. The 12-18% breaking elongation absorbs sudden tension changes during towing, protecting both the rope and the towed object. In rough seas, this elasticity prevents snapping under extreme loads.
2. Marine Fisheries
- Fishing Vessels: Deployed as trawl ropes and net hauler cables. Resistance to acids (from fish waste) and organic solvents (from cleaning agents) keeps the rope intact during long fishing voyages. In North Atlantic fisheries, it outlasts traditional ropes in cold, acidic seawater.
- Aquaculture: Secures fish cages and oyster farms. Dry - wet wear consistency means it performs equally well in tidal zones (constant wetting) and storage (dry), reducing replacement costs for aquaculture farms in Southeast Asia's monsoon - prone coasts.
3. Specialized Marine Projects
- Underwater Construction: Used for anchoring floating docks and submarine cable laying. Acid - alkali resistance withstands corrosive seabed environments (e.g., near industrial ports with polluted sediments), ensuring long - term stability for infrastructure like Singapore's marine renewable energy platforms.
Features
- Density: 0.975 g/cm³
- Good anti - UV properties
- Antimicrobial performance is good, not prone to mildew or moth damage
- Breaking elongation (%): 12-18
- Resistant to acid, alkali, and organic solvents
- Good abrasion resistance
- Wearability in dry and wet states is roughly the same
-
Material Synergy (Polyester + Polypropylene)
Wear Resistance Reinforcement: Polyester's outer layer provides high abrasion resistance (e.g., against sharp dock edges), while polypropylene's core offers flexibility. This double - layer design outperforms single - material ropes: in lab tests, it lasts 30% longer than pure polyester ropes in high - friction scenarios (e.g., repeated contact with ship hulls). Density Balance: At 0.975 g/cm³, it floats just enough for easy handling in water (unlike dense nylon ropes that sink) but has sufficient weight to stay taut during mooring (better than ultra - buoyant polypropylene ropes).
2. Environmental Resilience
All - Weather Performance: UV resistance + antimicrobial properties make it a "set - and - forget" solution for marine environments. In the Caribbean, where saltwater and sunlight accelerate rope decay, it maintains 90% of initial strength after 2 years - double the lifespan of common polypropylene ropes. Chemical Immunity: Resists acids (pH 2-3), alkalis (pH 11-12), and organic solvents (e.g., diesel spills). In industrial ports like Rotterdam, it survives contact with dockside cleaning chemicals that degrade standard ropes within months.

3. Operational Efficiency
- Consistent Wear in All Conditions: Dry - wet wear parity means no performance drop in rainy weather or after seawater immersion. For port cranes operating 24/7, this eliminates downtime from rope failure due to moisture - induced wear changes.
- High Elongation for Safety: 12-18% breaking elongation acts as a "shock absorber" in dynamic loads (e.g., sudden ship movements during docking). In Japan's earthquake - prone coastal ports, this reduces damage to mooring systems during tidal surges..
