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.

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.
