Achieve 4 times higher service life with Dyneema® SK78

This is why not all HMPE ropes are the same

Mooring ropes with Dyneema® SK78 massively outperform alternatives in abrasion and creep lifetime comparisons, without sacrificing strength and reliability. Find out how ropes with Dyneema® SK78 reduce costs while ensuring the safety of your crew and fleet.

Same strength ≠ same service life

To match the strength of a rope made with Dyneema® SK78, manufacturers who choose generic HMPE rope must adapt their rope construction by increasing both the lay length of the strands and the braid period of the rope. This weaker construction, plus the intrinsically lower performance of generic HMPE, reduces service life and increases costs.

Trusted strength

When measured, Dyneema® SK78 matches its claimed strength of 35 cN/dtex, while other generic HMPE fibers show significant variation, being up to 22% lower in strength.

HMPE fibers from Dyneema® SK78 have consistent quality with each supply, thus securing the high quality of the products made from them.


Abrasion lifetime

Ropes with Dyneema® SK78 show an abrasion lifetime that is 4 times longer than generic HMPE. That’s why Dyneema® SK78 is regarded as the industry benchmark.

Creep lifetime

Ropes made with Dyneema® SK78 have up to 4 times longer creep lifetime compared to generic HMPE.

How Dyneema® SK78 helps to prevent rope failure

The key to high-performance mooring and tow ropes is not only their design and construction, but also the fiber used to make them. Dyneema® is both the world’s strongest fiber and the only HMPE fiber scientifically engineered to overcome abrasion, bending fatigue, compression, and creep fatigue. Challenges that are familiar to all users of mooring and tow ropes.
