The need to prevent static buildup in moving applications has been increasing in modern production equipment. There are two main reasons for this:
ESD - avoidance of static charges in manufacturing processes for sensitive electronic components or assemblies
ATEX - prevention of explosive static charge in hazardous environments
ESD material tested with over 10 million cycles for the toughest requirements
Openable e-chains® with mounting brackets and interior separation in ESD and ATEX design available from stock
Standardised product - igumid ESD with PTB certificate
Proven over years of use in ATEX areas

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.
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.

Many other products of the complete igus® e-chains® range are available as custom designs also in ESD/ATEX 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.
