e-skin® corrugated tube for cleanrooms

Safe and abrasion-resistant guidance of cables in cleanrooms

► Abrasion-resistant
► IPA classification ISO class 1
► Compact and modular design
► Easy to open and flexible filling
► Resealable opening mechanism
To keep rooms free from particles, all machine parts - the energy supplies too - have to be abrasion-resistant. With the e-skin corrugated tube, systems are supplied with data, media and energy without unwanted particles contaminating the air.

The e-skin is a corrugated tube consisting of an upper and lower shell that form a complete enclosure when connected together. The simple resealable opening mechanism enables easy maintenance and inspection of the cables inside. e-skin has many advantages over conventional corrugated tubes and it is available in 3 different versions:

e-skin SK
For unsupported lengths up to 2m and installation space from 250mm

e-skin soft SKS
For unsupported length up to 1.3m and installation space from 150mm

e-skin Hybrid SKY
For unsupported length up to 1.4mm and installation space from 200mm

e-skin corrugated tube


Corrugated e-skin tube is available in an enclosed version and a version with chambers that can be opened individually. This flexibility is an innovation and unique on the market so far. Furthermore, e-skin has sufficient inherent rigidity and a defined bend radius (55 to 100mm).
The oval geometry ensures lateral stability. Short unsupported lengths are possible, even in small installation spaces. Conventional corrugated hoses do not offer this possibility. In addition, the energy supply is very quiet. Its noise level is only 29dB(A), 5dB(A) lower than that of conventional clean cables.

Why the e-skin corrugated tube?

1. Cleanroom ISO class 1.
Virtually no wear or abrasion
2. Two-piece corrugated tube.
Consisting of upper and lower shell
3. Circumferential mounting.
KMA mounting bracket, optionally with strain relief
4. Oval design
Prevents unintentional sideways movement
5. Fully enclosed.
Protection against dust and water ingress
6. Resealable opening mechanism.
Can be opened and closed like a zipper
7. Optional vertical separation.
Consisting of individual separators and full-width shelves
8. Minimisation of abrasion
With the new inner separation made of tribo-optimised iglidur material, the wear can be reduced by up to 80%.

IPA classification

Corrugated tube e-skin is certified according to the classification ISO class by IPA Fraunhofer Institute:
  • e-skin® SK SK28.068.02.1
  • e-skin® soft 0.SKS28.068.02.1
  • e-skin® hybrid SKY8.068.02.1
Tested at v = 0.5m/s, 1m/s and 2m/s all with ISO Class 1

Interior separation configurator for the e-skin

With the interior separation configurator for the e-skin corrugated tubes, you can create filling variants in just a few seconds and configure complete e-skin corrugated tubes with interior separation and mounting brackets.

  • Easy to fit
  • Avoidance of filling errors due to integrated filling guidance
  • Automatic creation of a parts list and drawing with dimensioning
  • Easy to submit an enquiry about and order the complete corrugated tube with chainflex cables and interior separations in the desired configuration.

Insight into igus cleanroom laboratory

Quality from the igus cleanroom laboratory

The new igus cleanroom laboratory was built by Fraunhofer IPA for the rapid development of particle-free motion plastics suitable for cleanrooms up to air purity class 1 according to ISO 14644-1.

Corrugated tube e-skin endurance test

Continuous test

The e-skin has been specially developed for cleanroom applications. In the laboratory, it withstood more than 6.4 million double strokes at 3m/s under realistic conditions.

e-skin corrugated tube bending test

Bending test

The standard bending tests show how flexible the e-skin soft e-skin soft is. It only bends, even under loads that would break other energy chains.

e-skin corrugated tube sound measurement

Noise level measurement

This test shows how quiet 'e-skin' corrugated tubes and 'e-skin flat' cleanroom cables are. Compared to competitors flat ribbon cables, the noise level of the e-skin flat is only 29dB(A).
