Dynamica-SK75 Ropes

 SK-75 Dyneema Rope - A fantastic Strong rope for dynamic applications.  

Made from Dyneema fibres, the Bridon Dynamica SK75 Rope is the most compact rope with excellent properties.  

As Dyneema is the strongest fibre in the world, ropes made from Dyneema have excellent strength, weight, UV stability and safety in the Dynamica. Combine this with its unique coating, and you get a rope with shape stability and increased abrasion resistance for a longer working life. 

12-Strand Dynamica SK75 Rope (except 6mm and 8mm, which are 8 Strand)

Features

Dynamica ropes are made from Dyneema fibres produced by DSM in Holland.

• Dyneema is the strongest fibre in the world. Dyneema's Ropes have excellent properties regarding strength, weight, Uv-stability (daylight), safety, abrasion, tension fatigue, and bending fatigue.
• Dynamica ropes are the most compact ropes in the world made from Dyneema.
• Dynamica ropes are produced in Denmark on state-of-the-art machinery to ensure the best obtainable quality.
• Dynamica ropes are coated with a unique coating that ensures shape stability and increased abrasion resistance for longer working life. Dynamica ropes are heat-set under tension to ensure maximum strength, durability and uniformity.

Strength

Dyneema is more than ten times stronger than steel per unit of weight. This means that Dynamica ropes have a slightly higher strength than a steel wire of the same dimension - but less than one-tenth of the weight. After two years of exposure, 80% of strength was retained.

Tension fatigue

Dyneema fibre can sustain many peak loads (loads close to the breaking strength). This gives a long life and a high safe working load. While steel wire can take 6,500 loads at 50 % of the maximum breaking load , Dynamica ropes can take 10 million cycles at the same load level. Dynamica ropes are, therefore, an excellent material for dynamic applications.

Safety

Dyneema has a very low elongation (2-3% at break). Dynamica ropes store little energy and therefore have little backlash - even at hundreds of tonnes of load. Using Dyneema, the amount of stored energy is much lower than nylon or steel wire ropes. This is a very important safety feature.

UV-stability

Dyneema has better stability in sunlight than other relevant fibre resistance to chemical substances.  Dyneema is resistant to chemical substances and will not be affected by oil, acids or other commonly used substances.

Abrasion

Dyneema has excellent abrasion resistance compared with other synthetic fibres (five times better than polyester).  Special care has to be taken, however, in order to ensure that it moves over clean non-rust surfaces etc. Sharp edges should be avoided.

Bending fatigue

Dyneema has good bending properties. however, it is recommended to bend over diameters of at least ten times the diameter of the rope.
