Typically, EMI and RFI shielding is used in medical equipment, military hardware, telecommunications systems, and anti-static applications. Resins or compounds with a high degree of electrical conductivity (low resistivity) are used in thick-film metallization and electrical interconnections. Dielectric compounds are used to form a barrier or isolator between electrical or electronic components. Call NEDC Fabricating Solutions For your next EMI/RFI Application

NEDC Fabrcating Solutions since 1982 has worked with every aspect of conductive elastomer materials technology from the earliest silver and silver/copper filled silicones to the latest and more cost-effective silver/aluminum and nickel/graphite composites. NEDC Fabrcating Solutions offers the most comprehensive selection and highest quality products available anywhere.. NEDC Fabrcating Solutions proprietary filler powder technology allows us to carefully control the composition, size, and morphology of the conductive particles. Their precise, uniform dispersion within the resinous binders produces materials with stable and consistent electrical and physical properties. In addition to EMI shielding, these materials will provide an environmental or pressure seal if required. NEDC Fabrcating Solutions’ conductive elastomers which deal with EMI/RFI shielding feature excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. All meet MIL-STD-810 requirements for fungus resistance. For those materials containing silver, both packaging and storage conditions should be similar to those for other silvercontaining components, such as relays or switches. The development of these composites is the result of decades of research and testing, both in the laboratory and in the field. They should be stored in sheet plastic, such as polyester or polyethylene, and kept away from sulfur-containing materials, such as sulfur-cured neoprene, cardboard, etc. To remove dirt, clean the elastomer with water or alcohol containing mild soap (do not use aromatic or chlorinated solvents). outlines the properties and specification limits of NEDC Fabrcating Solutions’ conductive elastomers. Our Applications Engineering Department is very accessible, and ready to assist with material selection and gasket design. We welcome your inquiry. NEDC Fabrcating Solutions’ array of conductive elastomers offers true flexibility in selecting the appropriate material for a specific application on the basis of cost and level of attenuation required. Price varies directly with shielding performance. All our conductive elastomer consists of a silicone, fluorosilicone, EPDM or fluorocarbon-fluorosilicone binder with a filler of pure silver, silver-plated copper, silver-plated aIuminum, silver-plated nickel, silver-plated glass, nickelplated graphite, or unplated graphite particles. These materials are produced in a virtually unlimited variety of molded, die-cut and extruded shapes and sizes.

Shielding against EMI emissions is commonly provided by a conductive enclosure. The separate parts of the enclosure must be electrically bonded together and grounded for the shielding to work. Disruptions in the electrical continuity between parts adversely affect shielding performance. Proper grounding of PCBs and shielding enclosure components is also a method for reducing board-generated EMI. However, improper or ineffective grounding may actually increase EMI emission levels, with the ground itself become a major radiating source. Many NEDC Fabricating Solutions shielding materials can be used for providing conductive grounding paths.

EMI/RFI Shielding is important in many industries. For example, EMI/RFI Shielding is necessary in telecomm because radio transmissions can hamper the reception of a signal by a recipient if the signals are near the same frequency. EMI/RFI Shielding may prevent incorrect frequencies from interfering with a device. Medically, in another example, hospital equipment must meet standards set by the FDA to prevent the machinery from being affected by cell phones, PDA’s, or other electronic devices. EMI/RFI Shielding helps to make such protections possible.

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). EMI and RFI may cause malfunctions in electronic devices. EMI and RFI cause suppression of signals generated internally in a device, external ambient interference with equipment operation, or emissions generated internally that will interfere with equipment operation. EMI and RFI are potential problems in any industry, and there is a premium on protective products and services from it. The electromagnetic waves generated by electronic devices may negatively affect other, similar, electronic devices. Call NEDC Fabricating Solutions for your next EMI project. 800-224-6332
