The wear or breaking load of our products depends on many parameters. Basically our rubber ropes have an elongation of approx. 100 %. The durability here depends on factors such as pretension and the frequency of elongation. However, factors such as humidity and temperature can also have a considerable impact on the force/elongation behaviour. In addition, the friction on our products has an impact on the durability.
Products made of 6 mm rubber cord generally have less wear and tear due to the higher mass in relation to the above factors. Fatigue of the force/elongation occurs later under the same conditions as with products made of 4 mm rubber cord.
The breaking loads are shown in the attached diagrams. These values serve as average values from our series tests.
A safety factor of 20 % must always be taken into account.
For all products, especially for outdoor use, we recommend a three-month visual inspection of the functional test.
