UHMWPE Rope
Leveraging resources from the high-strength synthetic fiber industry chain, this product is made from 100% ultra-high molecular weight polyethylene (UHMWPE, also known as Dyneema) fiber using a 12-strand braiding process. It covers a full diameter range of 2mm-150mm and boasts core advantages such as ultra-light weight, buoyancy, high strength and low elongation, corrosion and UV resistance, and wear and fatigue resistance. With a temperature range of -150℃ to 80℃, it is suitable for heavy-duty applications such as marine mooring, industrial lifting, outdoor rescue, and power line installation. Customization services for color, length, and logo are available, making it a lightweight alternative rope material for high-performance applications.
Core Product Features
- Material Advantages
1.100% UHMWPE fiber, density of only 0.97-0.98 g/cm³ (floats on water), water absorption < 0.1% (no performance degradation in wet conditions);
2.Resistant to acid, alkali, and petroleum-based chemical corrosion, and UV aging (strength retention rate ≥80% after 1500 hours of exposure);
3.Melting point 144-152℃, maintains stable toughness in environments from -150℃ to 80℃. - Process Highlights
1.12-strand single-braid structure, low rope torque, high flexibility, easy to knot/splice (splicing not possible for some small diameter versions);
2.Optional special coating on the surface to enhance wear resistance. - Performance Core
1.Ultra-high strength: 15 times stronger than steel wire ropes of the same diameter, 6mm version has a breaking strength ≥3.16kN (approximately 322kgf), 96mm version has a breaking strength of 510kN (approximately 52040kgf);
2.Low elongation: Elongation at 10% breaking strength is only 0.45%, effectively controlling sag, suitable for precise traction applications;
3.High wear resistance: 5 times more wear-resistant than ordinary nylon ropes, excellent bending fatigue resistance, and a service life 2-3 times longer than traditional ropes. - Practical Attributes
1.Multiple colors available (black in stock, red/blue/yellow, etc. available for customization), high-visibility colors suitable for outdoor/rescue scenarios;
2.Supports customized length and packaging as needed, weight per unit length is only 15% of steel wire ropes of the same strength, significantly reducing operational burden.
Specifications Table

Core Application Scenarios
- Maritime operations: Ship mooring ropes, towing ropes, buoy mooring ropes (floating properties facilitate recovery);
- Industrial lifting: Heavy load lifting ropes, winch towing ropes, equipment securing ropes (lightweight design reduces operational effort);
- Outdoor/Rescue: Climbing safety ropes, emergency towing ropes, paraglider lines (high visibility colors + high strength ensure safety);
- Power engineering: Live-line crossing ropes, insulated towing ropes (insulation performance passed 640kV withstand voltage test);
- Military/Special operations: Helicopter slings, paratrooper parachute lines, armored vehicle towing ropes (lightweight and easy to carry).
Precautions
- Usage Tips:
1.Melting point 144-152℃, avoid prolonged contact with high-temperature sources;
2.For long-term outdoor use, UV-stabilized coated versions are recommended;
3.Do not exceed the breaking strength; splicing is preferred over knotting. - Storage Requirements: Store in a dry environment at 0℃-30℃, off the ground, and avoid mixing with strong oxidizing agents;
