Technical environment and igumid G

The igumid G material, from which igus® energy chain cable carriers are made, possesses the following wide-ranging features to cope with a number of different environments: the ability to handle pressure and strenuous loads, abrasion resistance, sturdiness, stable behavior at high and low temperatures, and suitability for outdoor use. The igus® compound igumid G is partly suitable for inconsistent requirements. Numerous application examples, from refrigerator blocks to steel mills, prove this. In extreme cases, we also offer modifications and other igus® compounds as a solution.

Technical environment:

Fire resistance



Cold, heat

Explosion areas


Hot chips

Dirt, dust



Resistance to radiation

igumid G is very resistant to highenergy radiation. Under gamma radiation, in the range of 8 x 104 rd, the mechanical properties of igumid G change very little.

Flammability of igumid G

The flame-retardant characteristics of igumid G can be described using various classifications: All energy chains (except for E-Z Chains and Series 14) are made of igumid G. Test procedure VDE 0304 parts 3-5.70 - classification llc. Tested according to UL 94 "Standard Tests for Flammability of Plastic Materials for Parts in Devices and Appliances" classification 94 HB for 0.13 and 0.06 inch thickness of the body. Tested according to DIN 4102 "Fire Behavior of Building Materials and Parts" classification materials class B-2. For further requirements, please consult igus® for special solutions, such as materials with self-extinguishing properties (UL V2 or UL V0).

igumid NB:
UL 94 V2
UL 94 V0

Flammability of igumid NB

All E-Z Chains® and Series 14 Chains are made from the flame-retardant igumid NB material. These chains have the following flame-retardant classifications:

UL 94 classification - V2

VDE 0304 Parts 3-5.70 classification - llb

DIN 4102 flammability of materials - B2

Please ask for available V0 option.

Weathering, Temperature resistance

igumid G is very suitable for outdoor applications. In our experience, the mechanical properties of the energy chain are not impaired. igus® energy chains are used in applications as cold as -40°F. Installation may be eventually compromised at temperatures below -13°F. In such cases, we offer special solutions made from cold-elastic materials. 266°F continuous temperatures are possible. However, the mechanical values are reduced and the service life impaired.
