Specialty Silicone Products (SSP) announced that its SSP-2551, a nickel-aluminum fluorosilicone that combines EMI shielding with fuel, solvent and galvanic corrosion resistance, has been independently tested to 40 GHz and can be used with military electronic products that need to meet MIL-DTL-461 5.18 RE103 requirements for controlling electromagnetic interference (EMI). SSP’s EMI fluorosilicone has also been independently tested to MIL-DTL-83528 for elastomeric shielding gaskets, and to ASTM E595 for outgassing. All of these test reports, along with a new technical data sheet, are available via SSP’s website.
DLS Electronic Systems, an ANSI accredited laboratory under an ISO/IEC 17025 ANAB program, tested SSP-2551 at frequencies between 1 and 40 GHz. Shielding effectiveness declined at the upper end of this range; but SSP-2551 met or exceeded 100 decibels (dB) at all of the GHz frequencies that were tested. These independent test results indicate that SSP-2551 meets the requirements of MILDTL-461F section 5.18 RE103, radiated emissions, antenna spurious and harmonic outputs. This U.S. Department of Defense (DoD) standard applies to electronic, electrical and electromechanical equipment and subsystems.
