Tensile strength test report of robolink® wires
Martin Raak | 26. January 2012
robolink® wires were tested for tensile strength on the ZWICK tractor (nominal tensile strength > 3600 N).
The nipple connection was fixed with different adhesives (see installation instructions for the wires). The experiments were carried out at room temperature and at 80°C.

Test results:
| Wire fixed with: | Breaking strength at RT | Breaking strength at 80°C |
| 1) Loctite 401 | > 1.400 N | > 800 N |
| 2) Loctite 406 with primer | > 1.300 N | > 700 N |
| 3) Loctite 4204 | > 1.900 N | > 1.400 N |
| 4) Loctite 4204 with primer | > 1.400 N | > 1.000 N |
Conclusion:
igus® recommends the use of Loctite 4204 for installation of the wire nipple, especially because the use of wires/joints results in increased temperatures.
