BISCO® EC-2000 Series Conductive Silicones from Rogers Corp is industry''s first electrically conductive EMI/RFI shielding material available in wide, continuous rolls. Among the thinnest, softest materials being offered on the market today, these products also have excellent compression-set resistance, high shielding effectiveness, and easy processing to increase yields.
Recent trends in electronic design have brought electromagnetic interference (EMI) and its attendant shielding requirements to the forefront. The potential for interference has been greatly increased by the proliferation of electronic devices, miniaturization and portability of equipment, and developments in interconnect technology. The growing need for EMI gasketing is dictated by the trend toward increasingly higher operating frequencies (and shorter wavelengths) that result in decreased tolerances for even the smallest of gaps, seams, or slots in electronic equipment.
Within the wide array of EMI gasketing technologies available, the nickel-graphite filled EC-2000 Series Silicones offer high design flexibility because they are softer and more compressible than similar products. This means that a good mechanical seal can be obtained through compression of the gasket. In addition, these conductive elastomer sheets offer the combined advantages of high shielding performance, good flame resistance characteristics, and corrosion resistance.
Their availability as wide continuous roll goods makes processing easier and more economical, an advantage for fabricators and converters as well as for OEMs. From a converter''s perspective, not only do continuous roll goods afford the use of more efficient converting processes, they also eliminate the need for seaming molded sheets. This leads to better yields (lower scrap), and lower cost. Because these products may be easily die cut and delivered, they offer additional design versatility and decreased time to market for OEM designers.
The combination of extreme softness; availability in wide, continuous roll goods; very high shielding effectiveness; high compression-set resistance; and their availability in thin cross sections (down to 0.020 in.) means that BISCO EC-2000 Series Silicones can replace fabric-over-foam in many thin, intricately shaped applications. EC-2000 products fall in the 30-40 Shore A durometer range, and provide a range of thicknesses from 0.020-0.125 in. (0.50-3.18mm).
Rogers BISCO EC-2000 Series Silicones are ideal for applications including base stations, cell phones, computers, antennas, electronic devices, appliances, and medical and analytical/diagnostic equipment.
