Dynamica Rope Technical Data

Dynamica Rope is made from Dyneema fibre SK78 produced by DSM in Holland.

Dyneema is one of the strongest fibres in the world. The rope has excellent properties with regard to strength, weight, UV-stability (daylight), safety, abrasion, tension fatigue, bending fatigue. The most important data is shown below.

Dynamica Rope is the most compact Dyneema rope in the world.

Dynamica Rope is produced in Denmark on state of the art machinery, to ensure the best obtainable quality.

Dynamica Rope is coated with a unique coating that ensures shape stability and increased abrasion resistance for longer working-life.

Dynamica Rope is heat-set under tension to ensure maximum strength, durability and uniformity.


  • 4WD winch replacement ropes
  • Offshore applications
  • Fisheries
  • Bridles, Gilson lines, seam lines, front end meshes.
  • Lifting applications
  • Mooring
  • Towing
  • Safety

    Dyneema has a very low elongation (2-3% at break). It stores little energy and has therefore little backlash – even at hundreds of tonnes of load. This is a very important safety-feature.

  • UV Stability

    Dyneema has a better stability to sunlight than other relevant fibres. After two years of constant exposure 80% of the strength is retained.

  • Resistance to Chemical Substances

    Dyneema is resistant to chemical substances and will not be affected by oil acids or other substances.

  • Abrasion

    Dyneema has an excellent abrasion resistance compared with other synthetic fibres (five times better than polyester). Special care has to be taken, however, to ensure that it moves over clean, non abrasive, non-rusty surfaces etc.

    NB: Sharp edges etc. should be avoided.

  • Bending - Bending Fatigue

    Dyneema has good bending-bending properties. However it is recommended to bend over diameters of at least five times the diameter of the rope. 

The Dyneema Fibre Properties


Dyneema is more than ten times stronger than steel per unit of weight. This means that a Dyneema rope has a slightly higher strength than a steel wire of the same dimension – but less than one tenth of the weight.
DYNAMICA Ropes from Netmark are produced in both varieties of the Dyneema fibre SK62 and SK78.

Tension – Tension Fatigue
Dyneema can sustain a very large number of peak loads (loads close to the breaking strength). This gives a long life and a high safe-working load. While steel-wire can take 6500 loads at 50 % of the maximum breaking load a DYNAMICA Rope can take 10 million cycles at the same load level.

Dynamica Rope is therefore an excellent material for dynamic applications.
