HMPE 12 Strand Rope
HMPE ROPES
12 Strand HMPE ropes are the strongest commercial ropes available. HMPE rope is made from High Modulus Polyethylene which is a material that is composed of extraordinarily long molecular chains of polyethylene. In the 1950's the cordage industry began using HMPE and gel spinning it into high molecular weight polyethylene fibers and yarns for rope and cord making. HMPE ropes are very tough, stronger than steel, and have the highest impact strength of any thermoplastic presently made.
High performance ropes that are stronger than steel
HMPE rope has an extremely low density and it has a strength-to-weight ratio that is 8 time higher than high strength steel! The molecular alignment and gel spinning process allows the fibers to perform better and is the reason HMPE ropes, soft shackles and winch lines float, whereas steel wire sinks.
HMPE Ropes used for different products
HMPE is an amazing material and it is used to make artificial joints, body armor, high pressure hydraulic joints and seals and of course synthetic ropes, cords and lines for a variety of industries.

Benefits and Features of HMPE ROPE
- HMPE has the lowest stretch of any rope available
- Low creep
- Soft hand
- Torque free
- Easy splicing
- Neutrally buoyant in water
- Select sizes of 12 strand HMPE ropes are ABS & DNV type approved
This 12 strand rope is the highest strength synthetic rope available and is manufactured from High Modulus Polyethylene (HMPE) that has been enhanced by a recrystallization process.
HMPE 12 strand is delivered standard with a polyurethane finish and is easily spliced using a simple lockstitch type splice, 4-3-2 or 5-4-3 tuck splice. It's soft, torque free braided construction provides easy handling.

High Modulus Polyethylene Elasticity
HMPE fibers are very inelastic, they do not stretch much at all. After a rope is braided and spliced, there is typically a "constructional stretch" as the rope is loaded past 40% MTS for the first time, which can lead to up to 5% elongation. Once this constructional stretch has been removed, there will be virtually no stretch in an HMPE rope.
Ultra High Molecular Weight Durability
HMPE ropes are extraordinarily durable. HMPE also has a low coefficient of friction, which means it has excellent wear properties and can have a slippery feel. As with all rope, HMPE line can be susceptible to cutting if put under tension while on a sharp edge.
