Polyethylen med ultrahøj molekylvægt (UHMWPE / HMPE)
UHMWPE / HMPE reb er en stærk innovation inden for brancher, hvor styrke og holdbarhed er afgørende. Dette reb er kendt for sine exceptionelle egenskaber, der kombinerer høj brudstyrke, lav vægt og fremragende modstandsdygtighed over for slid og abrasion.
Tre centrale fordele
-
Høj styrke — 15× stærkere end stål ved samme vægt
-
Lav vægt — Flyder på vand og er nem at håndtere
-
Holdbar — Fremragende modstandsdygtighed over for UV, kemikalier og slid

Høj ydeevne
Vigtigste egenskaber ved HMPE-reb
Høj styrke
HMPE-reb har imponerende trækstyrke. De er mindst otte gange stærkere end standard stålwirereb af samme vægt. Denne høje styrke gør det muligt at anvende tyndere og lettere reb uden at gå på kompromis med bæreevnen.
Lav vægt
På trods af den høje styrke i HMPE-reb er de bemærkelsesværdigt lette. De kan veje blot en brøkdel af stålwirereb, hvilket gør dem lettere at håndtere, transportere og installere. Denne reducerede vægt går ikke ud over ydeevnen – rebbene bevarer deres strukturelle integritet under tung belastning.
Slid- og abrasionsbestandighed
Rebene udviser fremragende slidstyrke, hvilket giver dem mulighed for at modstå barske forhold og ru overflader uden hurtig nedbrydning. Deres slidstyrke forlænger rebbets levetid og reducerer behovet for hyppig udskiftning. HMPE-reb er op til 15 gange mere slidstærke end kulstofstål.
Kemisk bestandighed
HMPE-reb har en molekylær struktur, der gør dem i stand til at modstå en bred vifte af kemikalier, herunder rengøringsmidler, mineralsyrer og olier. Denne kemiske bestandighed sikrer, at rebets ydeevne forbliver konsistent, selv ved udsættelse for aggressive stoffer.
Lav strækning
Med minimal forlængelse under belastning holder HMPE-reb deres længde og form selv ved høj spænding. Denne egenskab er vigtig i anvendelser, hvor præcision og stabilitet er påkrævet, såsom fortøjning og løfteoperationer.
Flydeevne
Massefylden af UHMWPE-reb er lavere end vands, hvilket gør, at rebet flyder. Denne egenskab er særligt fordelagtig i marine anvendelser, hvor flydende reb forbedrer sikkerheden og brugervenligheden.
Ofte stillede spørgsmål om HMPE-reb

HMPE stands for High Modulus Polyethylene, also known as UHMWPE (Ultra High Molecular Weight Polyethylene). It's a synthetic fibre with extremely long molecular chains, all aligned in the same direction — this is exactly why HMPE is so incredibly strong for its weight. Dyneema is a well-known brand name based on the same UHMWPE fibre, produced by DSM.

Prorope offers four HMPE/UHMWPE products:
- Prorope HMPE rope — our own 12-strand braided HMPE rope, available from 4 mm to 16 mm
- HMPE rope with polyester cover — core-and-cover rope for better handling and abrasion resistance, from 2 mm to 5 mm
- HMPE/UHMWPE cord 5 mm navy/gold — a special colour variant, ultra-strong and direct from stock
- UHMWPE rope with polyester cover 3 mm — compact and lightweight core-and-cover rope
All ropes are sold per metre and available direct from stock.

We tested our own 4 mm Prorope HMPE rope (article number T-20182) in our own laboratory in March 2026. Averaged over 5 tests, the breaking strength came out at 17.926 kN — the equivalent of more than 1,827 kg. That's exceptionally high for a rope only 4 mm in diameter.
For comparison: a 4 mm core-and-cover HMPE rope from another supplier averaged 5.586–6.698 kN in our tests. The 12-strand braided construction of our own brand delivers significantly higher breaking strengths.
-
This 5 mm cord has been extensively tested (December 2025). Without a knot, the average breaking strength came out at 9.266 kN (~945 kg) over 5 tests. With pre-tensioning this rose to 10.642 kN (~1,085 kg).
With a knot, the breaking strength dropped to an average of 4.834 kN (~493 kg) — a loss of around 48%. This confirms once again: always use a splice or softshackle instead of a knot.
-
We have measured this on multiple HMPE variants. On the 3 mm core-and-cover rope (black cover), the breaking strength dropped from an average of 4.188 kN without a knot to 1.880 kN with a knot — a loss of around 55%.
On the 5 mm navy/gold cord, a knot caused around 48% loss of breaking strength. Always prefer a spliced loop (splicing costs only around 10% of breaking strength) or a certified softshackle.
-
Our own tests reveal an important safety point: on core-and-cover HMPE rope, the core can break while the polyester cover remains fully intact. This means a broken rope can look completely undamaged from the outside.
If you aren't sure whether a core-and-cover rope has been heavily loaded or dropped, don't use it again without inspection. This is a known characteristic of all core-and-cover constructions.
-
Yes. The specific gravity of HMPE is 0.97 g/cm³ — slightly lower than water. That makes HMPE rope one of the few high-performance ropes that naturally floats. This makes it especially suitable for marine applications, watersports and situations where a floating rope improves safety.
-
HMPE rope has very low stretch at break: typically 2–4%. This is significantly less than polyester (~10–15%) or nylon (~25–35%). Thanks to this minimal stretch, the rope holds its position under load, which is essential for winching, hoisting and precision applications.
Note: for recovery situations where shock absorption is desirable, a kinetic rope with more stretch is the better choice.
-
Yes. HMPE is naturally well-resistant to UV radiation. On the page we list this as 100% UV-resistant. On the core-and-cover variants, the polyester cover provides extra protection for the core. Prorope only sells HMPE ropes with good UV resistance — no compromise on quality.
-
Yes. HMPE has excellent chemical resistance: it withstands detergents, mineral acids and oils. Saltwater has no adverse effect on breaking strength or service life, which makes HMPE ideal for marine and offshore applications.
-
The Prorope HMPE rope (4–16 mm) is a 12-strand braided rope without a cover: maximum breaking strength, slightly stiffer in character, ideal for winching, hoisting and heavy-duty applications.
The HMPE rope with polyester cover (2–5 mm) has an HMPE core with a polyester outer cover. This makes it more supple, easier to knot and more resistant to abrasion. The covered variant is ideal when handling and core protection matter more than absolute maximum strength.
-
Yes. All our HMPE rope is sold per metre, with no minimum order quantity. Orders placed before 13:00 ship the same day.
