NEDC Works With EMI
May 7th, 2009 by Editor
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.
