ESD Drag Chains Made from Shock-Resistant Materials

As early as 1992, the igus® GmbH, together with the PTB (Physikalisch-Technische Bundesanstalt) in Braunschweig, conducted measurements of the electrical surface leakage resistance for igus® e-chains® with the special material igumid GC, supplemented by additional certifications in 1998 and 1999 according to DIN 53482 and the guidelines for static electricity "ZH1/200" of the Federation of Trade Associations.

As part of further innovation, the material igumid ESD was certified in May 2002 by the PTB (Physikalisch-Technische Bundesanstalt). In many mechanical requirements, the igumid ESD surpasses even the standard material igumid GLW and has been tested in the igus® technical center with over 10 million cycles.

Conductivity of igus® products made of igumid ESD
Contrary to the conductive surface coatings for temporary use or the briefly incorporated static inhibitors, the applied additive enables a lasting and maintenance-free conductivity for years. However to ensure conductivity in an e-chain®, it is not enough if only the individual components exhibit conductivity, but the entire e-chain® must have a continuous conductivity from one end to the other. All products in this catalog are optimized in this regard, and the continuous conductivity is measured and documented by a 100% test before delivery.

Only the e-chains® that have passed this test are given the seal and delivered. Color of the igumid ESD products: similar to RAL7015, slate gray for safe differentiation from standard materials.

Structural design
Not only the material is important for a safe electrostatic discharge. The structural design is also critical for a truly safe use. The e-chains® from the E4.1 modular kit ensure a permanently constant discharge, since its chain links have a positive-fit connection with each other. Through its patented "tongue and groove" system, the inner link engages the outer link, whereby a discharge is guaranteed even after several million cycles. The e-chains® from the E2/000 range ensure a safe discharge due to the extremely low clearance between the pin and the hole of the chain links.
products made of igumid ESD 100% of the produced ESD e-chains® are checked for
their continuous conductivity "from one end to the other"

Nothing suitable in the bearing range?

Many other products of the complete igus® e-chains® range are available as custom designs also in ESD versions. igus® would be pleased to make an offer for your custom-made product, if technically possible, in the required quantity. The significantly improved profitability, as well as the rapid availability of the bearing range - particularly in the spare parts supply - should always be the first choice.
