igus® B.V.
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
Short delivery times: 24hrs , from stock
7:00 am to 8:00 pm - ordering and delivery service
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.
