超高分子量聚乙烯HMPE (High-modulus polyethylene) fibres are produced by ultra-high molecular weight polyethylene (UHMWPE). It has a very low coefficient of friction and is extremely resistant to abrasion. The strength is higher than that of conventional steel wire rope and the corresponding weight is up to 7 times lower. Its better handling characteristics, buoyancy and increased safety (no lash back) are especially appreciated in towing and mooring applications.

The cover can be made from polyester or HMPE, giving the rope extra protection against abrasion and thus increasing the service life of the rope.

Features of UHMWPE Rope

· Stronger: For the same dia., the strength is the same as the wire rope.

· Lower Elongation: The breaking elongation is close to the wire rope.

· Lighter: In the same strength, the weight is only 1/8 of the wire rope, 1/4-1/5 of the nylon rope or polyester rope, and 18%-20% of the polypropylene rope.

· Smaller: In the same strength, the dia. of the UHMW PE rope is 55%-60% of the nylon rope or polyester rope, and 45% of the polypropylene rope.

· Excellent wear resistance: The wear life of UHMWPE rope is 4 times that of steel wire rope and rope made of ordinary HMPE and polyester.

· Good chemical resistance: Due to its molecular structure, UHMWPE can withstand most chemicals, including detergents, mineral acids and oils. However, it can be corroded by strong oxidants.

Applications of UHMWPE Rope

· Towing heavy objects, especially boats

· Traction, winch, traction line

· Cranes and pulley systems that need to lift heavy objects

· Specialty Rigging Line

· Anchor rope

· Replace the wire rope
