Rogers Corp will launch its new and exciting line of electrically conductive silicones at Electronica.

Bisco EC-2000 Series silicones are the industry's first electrically conductive EMI/RFI shielding materials available in wide, continuous rolls.

These products are among the thinnest, softest materials being offered on the market today.

They have the additional features of 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 growing need for EMI gasketing is dictated by the trend towards increasingly higher operating frequencies (and shorter wavelengths) that result in reduced 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.

EC-2000 products fall in the 30-40 Shore A durometer range, and provide a range of thicknesses from 0.50 to 3.18mm.

They provide the ideal shielding solution for applications including base stations, cell phones, computers, antennas, electronic devices, appliances and medical and analytical/diagnostic equipment.
