Product Detail

Products Highlights

Sinkable Security : Specific gravity of 1.38 (Sinks in water). This allows the line to stay submerged below the surface, avoiding surface debris and reducing the risk of interference with small surface craft.
Low Heat Generation: Excellent thermal properties ensure that the rope dissipates heat efficiently during high-tension surging, preventing internal fiber fusion.
Soft Handling & Zero Shrinkage: Pre-stabilized fibers ensure the rope won’t shrink or harden over time, remaining flexible and easy for the crew to splice and coil.

Core Application Scenarios & Strategic Advantages

Application Scenario	Strategic Advantage	Juli Sling Benefit
Long-Term Terminal Berthing	Exceptional UV Stability	Polyester has the highest natural resistance to solar degradation. It maintains structural integrity in tropical or high-UV regions far longer than PP or Nylon.
High-Friction Harbor Operations	Superior Abrasion Resistance	High-tenacity filaments resist fraying and “fuzzing” when passing through fairleads or around bitts, significantly extending the rope’s service life.
Variable Tide & Surge Control	Low Elongation & Precision	Lower stretch compared to Nylon ensures the vessel remains accurately positioned against fenders, reducing the risk of drift during heavy swells or tidal shifts.
Heavy Rain & High-Humidity Ports	100% Wet-Strength Retention	Unlike Nylon, which loses strength when wet, Polyester maintains 100% of its rated breaking load in water and does not shrink or harden after drying.
Sub-Surface Line Management	High Specific Gravity (1.38)	As a “sinkable” fiber, it stays below the water surface, preventing entanglement with propellers or surface debris in busy shipping channels.
