ProductsDynamica SK75 Rope12 - Strand Dynamica SK75 RopeDYNAMICA ropes are made from Dyneema ® fibres produced by DSM in Holland.Dyneema ® is the strongest fibre in the world. Ropes from Dyneema ® have excellent properties withregard to strength, weight, UV-stability (daylight), safety, abrasion, tension fatigue, 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 bestobtainable quality.DYNAMICA ropes are coated with a unique coating that ensures shape stability and increasedabrasion resistance for longer working life. DYNAMICA ropes are heat-set under tension to ensuremaximum strength, durability and uniformity.StrengthDyneema ® is more than 10 times stronger than steel per unit of weight. This means that DYNAMICAropes have a slightly higher strength than a steel wire of the same dimension - but less than onetenth of the weight. DYNAMICA ropes are produced from SK75 from DSM Dyneema.Tension fatigueDyneema ® fibre 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 steelwire can take 6,500 loads at 50 % ofthe 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.SafetyDyneema ® has a very low elongation (2-3 % at break). DYNAMICA ropes store little energy andtherefore has little backlash - even at hundreds of tonnes of load. Using Dyneema ® the amount ofstored energy is much lower compared to nylon or steel wire ropes. This is a very important safetyfeature.UV-stabilityDyneema ® has a better stability to sunlight than other relevant fibre. After two years of exposure 80%of the strength is retained.Resistance to chemical substancesDyneema ® is resistant to chemical substances and will not be affected by oil, acids or othercommonly used substances.AbrasionDyneema ® has an excellent abrasion resistance compared with other synthetic fibre (five timesbetter than polyester). Special care has to be taken, however, in order to ensure that it moves overclean nonrust surfaces etc. Sharp edges etc. should be avoided.Bending fatigueDyneema ® has good bending properties. However, it is recommended to bend over diameters of atleast 10 times the diameter of the rope.22 Fibre Rope
