Dyneema® is more than 10 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 retained.
Dyneema® 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 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.
Dyneema® has a very low elongation (2-3% at break). Dynamica ropes store little energy and therefore has little backlash - even at hundreds of tonnes of load. Using Dyneema® the amount of stored energy is much lower compared to nylon or steel wire ropes. This is a very important safety feature.
Dyneema® has a better stability to 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.
Dyneema® has an excellent abrasion resistance compared with other synthetic fibre (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.
Dyneema® has good bending properties. however, it is recommended to bend over diameters of at least 10 times the diameter of the rope.
