NCROPE double braided UHMWPE rope is a premium high-performance rope constructed with a UHMWPE (Ultra-High Molecular Weight Polyethylene) fiber core and a tightly braided protective cover, delivering exceptional tensile strength, extremely low stretch, and outstanding abrasion resistance for the most demanding marine, offshore, and industrial applications.
With a strength-to-weight ratio 8 to 10 times higher than steel wire rope of the same diameter, our double braided UHMWPE rope floats on water, resists UV degradation, chemicals, and moisture, and remains flexible even in sub-zero temperatures. It is engineered for vessel mooring, tugboat towing, offshore platform anchoring, winch lines, crane ropes, fishing gear, and heavy-duty rigging slings.
NCROPE offers full customization including diameter, length, cover material, color, eye splicing, end fittings, load-rating configuration, and private-label packaging for marine distributors, offshore operators, fleet managers, and OEM brands worldwide.
Double braided UHMWPE rope is constructed using a two-layer braided design: an inner core made from high-strength UHMWPE fibers carries the primary load, while an outer braided cover protects the core from abrasion, UV exposure, and external damage. This construction differs from single-braid (12-strand) UHMWPE rope by adding a protective outer layer, making it more durable in high-wear applications.
UHMWPE (Ultra-High Molecular Weight Polyethylene) fiber, also known as Dyneema or Spectra, is one of the strongest man-made fibers in the world. It offers extremely low elongation (approximately 3.5-4% at break), high energy absorption, and excellent resistance to chemicals, UV radiation, and moisture. The double braid construction combines the strength of UHMWPE with the protective benefits of a braided cover, resulting in a rope that is both strong and durable.
Used for vessel mooring, tugboat towing lines, offshore platform anchor lines, and ship-to-shore operations where high strength and low stretch are critical for safety.
Suitable for crane hoist lines, winch ropes, heavy-lift slings, and load-securing applications in construction, mining, and industrial manufacturing environments.
Ideal for marine towing, vessel salvage, and recovery operations where ropes must absorb shock loads without breaking or excessive elongation.
Used in commercial fishing gear, aquaculture pen lines, trawl warps, and net rigging where saltwater resistance and long service life are essential.
Our double braided UHMWPE rope is manufactured from premium ultra-high molecular weight polyethylene fiber with the following key characteristics:
Core: High-strength UHMWPE fiber core with strength-to-weight ratio 8-10x higher than steel wire rope
Cover: Dense braided outer cover for abrasion protection and extended service life
Elongation at break: Approximately 3.5-4%, providing low-stretch performance under sustained load
Specific gravity: 0.97 g/cm3, floats on water
Temperature range: Remains flexible at temperatures down to -43C
Water absorption: Zero absorption, no rotting or mildew
Chemical resistance: Resistant to acids, alkalis, saltwater, and most industrial chemicals
UV resistance: Excellent resistance to ultraviolet degradation
Diameter (mm) | Breaking Strength (kg) | Weight (g/m) | Cover Option |

10 | 4,000 | 55 | UHMWPE / Polyester |
12 | 6,000 | 78 | UHMWPE / Polyester |
14 | 8,500 | 105 | UHMWPE / Polyester |
16 | 11,000 | 135 | UHMWPE / Polyester |
20 | 17,000 | 210 | UHMWPE / Polyester |
24 | 25,000 | 300 | UHMWPE / Polyester |
Custom diameters, lengths, and cover configurations available upon request. Breaking strengths are approximate and may vary by fiber grade and construction.
Maximum strength-to-weight ratio: 8-10x stronger than steel wire rope of the same diameter, significantly lighter and easier to handle
Extremely low stretch: 3.5-4% elongation at break ensures stable tension under sustained load, critical for precision operations
Dual-layer protection: Braided outer cover shields the load-bearing core from friction, sharp edges, UV, and contamination
Floats on water: Specific gravity of 0.97 g/cm3 makes retrieval easy and prevents rope loss in marine environments
Zero water absorption: No rotting, mildew, or strength loss when wet, unlike natural fiber or polyester ropes
Chemical and UV resistant: Withstands saltwater, acids, alkalis, and prolonged sun exposure without degradation
Flexible in cold temperatures: Maintains flexibility down to -43C, suitable for arctic and winter operations
High-strength splicing: Eye splices retain over 90% of the breaking strength for secure end terminations
Feature | Double Braided UHMWPE | 12-Strand Single Braid UHMWPE |
|---|---|---|
Construction | Inner core + outer cover | Single layer, 12 strands |
Abrasion resistance | Higher (covered core) | Moderate (exposed fibers) |
Strength efficiency | ~85-90% of fiber strength | ~90-95% of fiber strength |
Handling flexibility | Softer, easier to coil | Firmer, holds shape |
Best for | High-wear, critical load applications | Clean environment, maximum strength |
1. Determine the required breaking strength: Calculate the working load (typically 10-20% of the breaking strength for safety) and select a rope with adequate margin.
2. Choose the right diameter: Larger diameters provide higher strength but increased weight and cost. Match the diameter to your equipment winch, cleat, or fitting sizes.
3. Select the cover material: UHMWPE cover offers maximum strength and low friction; polyester cover provides better grip and heat resistance for winch applications.
4. Specify end fittings: Eye splices, thimbles, shackles, or custom terminations should match your connection points and load requirements.
5. Consider operating environment: For extreme abrasion or chemical exposure, discuss specialized cover treatments or coatings with our technical team.
