What are the technical specifications of UHMWPE?

UHMWPE is a polyolefin fibre, consisting of extremely long chains of overlapping polyethylene, aligned in the same direction, which makes it one of the strongest rope options available.

Thanks to its molecular structure, UHMWPE is resistant to most chemicals, including detergents, mineral acids and oils. It can, however, be corroded by strong oxidising agents.

The HMPE fibres have a density of only 0.97 g cm−3 and have a coefficient of friction that is lower than nylon and acetal. Its coefficient is similar to that of polytetrafluoroethylene (Teflon or PTFE), but it has much better abrasion resistance.

The fibres that makeup Ultra High Molecular Weight Polyethylene have a melting point of between 144°C and 152°C, which is lower than many other polymer fibres, but they have no brittle point when tested at an extremely low temperature (-150°C). Most ropes will not be able to maintain their performance in temperatures below -50°C. UHMWPE rope is therefore recommended for use between -150 and +70 °C, as it will not lose any of the high molecular weight properties in this range.

UHMWPE is actually classed as a speciality engineering plastic, used for many other functions beyond rope manufacturing. In fact, medical-grade UHMWPE has been used in joint implants for many years, particularly in knee and hip replacements. This is due to its low friction, toughness, high impact strength, resistance to corrosive chemicals and excellent biocompatibility.

UHMWPE Rope Main Usage:

Typical applications of Ultra high molecular weight polyethylene (UHMWPE) include:

Towing heavy objects, especially vehicles and vessels
Winching, both onshore and offshore
Mooring - it is recommended by OCIMF for safe mooring of tanker vessels
Cranes and pulley systems where heavy lifting is required
Wire rope replacement – it is stronger and more affordable
Anchor rope
Deepwater installations
Lifting slings and cables
Paragliding lines
Trawl nets and ropes
Synthetic link chains
Pulling up the mainsails of yachts
Kickers – for pulling on tension on the sail and boom
Strops – replacing sail ties to connect the sail to the boat
Conveyor lines
Fishing lines -
Spear lines on spear-guns
Watersports (wake-board and kite surfing lines)
Marine equipment
Operations that require regular harsh cleaning in a wet environment
