Eccosorb SF-U

Frequency Key features Thickness Service T° In or outdoor
1 - 26 GHz High mechanical strength, excellent abrasion resistance Dependant on Resonant Frequency -40°C to 120°C In/Out
Very narrowbanded, magnetically loaded, resonant urethane absorber

Eccosorb SF-U is a series of thin free space resonant absorbers.  These magnetically loaded narrowbanded absorbers reflect 1% or less of normally incident energy (at least 20 dB down) at design frequencies when intimately backed to a metal surface.

Eccosorb SF-U has increased abrasion and fuel resistance compared to its silicone counterpart Eccosorb SF, with only a slight loss of flexibility.  In order to function properly, Eccosorb SF-U should be attached to a metal surface.  If required an integral reflective backing (ML) can be provided as well as a Pressure Sensitive Adhesive (PSA) for easy attachment.

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.
On special order, other resonant frequencies from 0.7 to 40 Ghz can be supplied.
