These silicone rubber sheets are designed to be bonded to flat or curved metallic surfaces to reduce the reflectivity in a narrow band of frequencies. Eccosorb SF reflects -20 dB or less of normally incident microwave energy at the design frequency in the range of 1 to 26 GHz.Applications include lining radar nacelles (particularly where high power is present), lining of cavity backed and shrouded telecommunication antennas, lining metal surfaces to attenuate surface currents, and for lining magnetron housings to prevent detuning.Note: ECCOSORB SF is NOT designed for use inside a cavity. While the material will perform well because of the high electrical parameters, this material is specified on performance and each batch is tuned for thickness. Therefore batch variations will cause thickness variations, which could lead to clearance issues inside a cavity. Please consult a Sales Engineer for assistance in selecting a proper material.
– High power performance
– Narrow band performance
– Low outgassing properties
