New Developments in EMI Shielding from Tenneco
Latest technologies combine EMI shielding with reduced weight and water repellence

SOUTHFIELD, Michigan, June 17, 2019 … Tenneco’s (NYSE:TEN) Powertrain division has enhanced its electromagnetic interference (EMI) shielding portfolio in response to the aviation market’s demand. It will be showcased alongside highlights from Tenneco Powertrain’s comprehensive range of systems protection products at the 2019 Paris Air Show, Hall 4, booth G41 from June 17-23.

“By optimizing the construction and arrangement of each element in the material, we have been able to drive down weight while maintaining exceptional shielding performance across both high and low frequencies,” said Janice Maiden, Senior Vice President, Global Systems Protection, Tenneco Powertrain division. “We have also focused on maintaining water repellent properties, which minimizes the risk of icing or water ingress degrading system performance.”

EMI shielding protects against the unintentional generation and reception of electromagnetic disturbances in a circuit or wiring harness. These disturbances can create a variety of unwanted effects, such as causing computer-controlled systems to power-up or -down. As the use of electronic controls and equipment continues to increase on aircrafts, there is a growing need to ensure that the electrical and electronic architecture is protected from EMI, usually by specially designed protective sleeving.

Tenneco’s range of materials for effective EMI management combines EMI shielding with a number of other valuable properties. The composition and specification is tailored for specific applications and has been developed and refined over many years.

The most recent developments are the ROUNDIT® EMI XWS and NX EMI products with optimized, weight-saving wire filaments. The shields are all self-wrapping, so can be easily installed on wire harnesses, while allowing the protected assembly to be re-opened for inspection and maintenance. The sleeving can be installed during initial harness assembly or after complete systems are assembled, in the event that an EMI concern is detected and correction required. Their design offers an innovative solution to the protection of breakout areas and enables users to stock a limited range of sizes to cover a wide range of cable and wire diameters. Thanks to their unique geometry and metal insertion, they are also easy to combine with existing solutions.

ROUNDIT® 2000 NX EMI provides mechanical protection and EMI shielding for wire and cable bundles. The outer layer, which supplies the abrasion resistance, is manufactured from PPS (polyphenylene sulphide) monofilaments and Nomex® fibers with a water repellent treatment meeting the latest industry standards and requirements. The inner layer is composed of nickel plated copper (Cu/Ni), which provides EMI insulation. The outer layer construction with a 100 percent covering ratio provides excellent cut-through and abrasion resistance. ROUNDIT 2000 NX EMI is also available with an internal layer of PTFE tape (polytetrafluorethylen), allowing wire harnesses to be protected from the inner metal layer.
