Product Description
Eccosorb SF-5.5 is a black silicone free-space elastomer microwave absorber grade tuned for 5.5 GHz. It is used on flat or curved metallic surfaces for narrow-band reflectivity reduction and surface-current attenuation. Standard 12X12 NA part 21458167 has a typical density of 3.50 g/cm^3, Shore A hardness of 73, a maximum operating temperature of 163 deg C, and listed reflectivity greater than -20 dB at 5.5 GHz. That standard part measures 305 x 305 mm and 2.33 mm thick. Laird also lists PSA and on-drawing configuration options for the grade.
Key features
- 5.5 GHz Design Frequency: The grade is tuned for free-space absorption at this frequency.
- 163 deg C Maximum Operating Temperature: Standard part 21458167 carries this listed operating-temperature limit.
- About 2.33 mm Standard-Part Thickness: Part 21458167 is supplied as an approximately 305 x 305 mm sheet at this thickness.
Applications
Bonding to flat or curved metallic surfaces for narrow-band microwave reflectivity reduction; radar nacelles; cavity-backed or shrouded telecommunications antennas; surface-current attenuation on metal surfaces; magnetron housings. Not specified for use inside a cavity.
