HMPE core performance characteristics：

• High strength and light weight

Strength far exceeds that of traditional steel wire ropes: At the same weight, the breaking strength of HMPE ropes is 1.5-2 times that of high-quality steel wire ropes, and can withstand huge tensile forces.

Light weight: The density is only 0.97g/cm³, which is lighter than water. It can float in water, which is convenient for water operations (such as ship mooring, water rescue), and it is more labor-saving to carry and operate.

• Chemical corrosion resistance

It has good resistance to chemical substances such as acids, alkalis, and salts, and is not easily corroded. It is suitable for chemical environments, seawater (containing salt) and other highly corrosive scenes, and its service life is much longer than that of traditional chemical fiber ropes (such as nylon ropes).

• Abrasion resistance and low friction coefficient

The surface is smooth and the friction coefficient is low. It is not easy to wear when in contact with other objects, and it can also reduce scratches on the tied/pulled objects (such as yachts and precision equipment).

It has excellent wear resistance. When used repeatedly or in contact with rough surfaces, the wear rate is slower than that of polyester ropes, polypropylene ropes, etc.

• UV and weather resistance

The specially treated HMPE rope can resist UV aging. When exposed to sunlight, wind and rain for a long time outdoors, its performance decays slowly. It is suitable for open-air operations or long-term outdoor use scenarios (such as mountaineering and high-altitude operations).

• Low elongation

The elastic elongation is low (usually less than 3%), the deformation is small after force, and the tension can be maintained stably. It is suitable for scenarios that require precise control of position or fixation (such as lifting, hoisting, and precision equipment positioning).

HMPE common application areas：

• Ocean and maritime

Ship mooring and towing: replace traditional wire ropes, reduce the load on the hull, and resist corrosion in seawater environments.

Fishing: As trawl ropes and fishing lines, they are strong and floatable, making them easy to operate.

Water rescue: used for lifelines and assault boat traction, and their lightweight characteristics are suitable for emergency rescue scenarios.

• Industry and lifting

Lifting and hoisting: used for the lifting of heavy equipment and steel structures, and low elongation ensures the stability of the lifting process and avoids the shaking of goods.

Bundling and fixing: replace chains or wire ropes, and are used for bundling heavy goods (such as steel and machinery) in truck transportation to reduce damage to goods.

• Outdoor and sports

Mountaineering and rock climbing: As safety ropes and anchor ropes, they are strong and light, reducing the weight of climbers.

Extreme sports: such as kite surfing and paragliding traction ropes, which can withstand the tension in high-speed movement.

• Military and security

Military equipment traction, airborne equipment fixation, and border patrol obstacle ropes, rescue ropes, etc., rely on high strength and weather resistance to adapt to complex environments.

Precautions for use and maintenance

• Avoid high temperature environment: HMPE fiber has a low melting point (about 130-140℃), so it should be kept away from open flames and high-temperature objects (such as welding points) to avoid long-term exposure to high temperature environments, which may lead to a decrease in strength.

• Prevent excessive bending: Repeated folding or severe bending may cause internal damage to the fiber and reduce strength. It should be rolled into a large-diameter coil when stored to avoid sharp bends.

• Regular inspection: Check for wear, cuts, fiber breakage, etc. before use. If damage is found, it should be replaced immediately and should not be overloaded (refer to the rated breaking strength of the rope).

• Avoid long-term contact with strong acids and alkalis: Although it has strong corrosion resistance, long-term immersion in concentrated acids and alkalis may still affect performance. Clean it in time after use.
