Eccosorb FGM-40 is a thin, flexible, broadband, magnetically loaded silicone absorber.  Eccosorb FGM-40 (1mm thickness) operates as free space absorbers in the range of 4.0 to 18.0 GHz.  The thinner Eccosorb FGM-40 will easily conform to contoured surfaces and can be bonded to metallic or non-metallic structures.  Eccosorb FGM-40 is completely impervious to moisture and can be subjected to outdoor environments and high altitudes including space with no adverse effects.  It can be easily cut with a knife or die and can be held in place with an optional Pressure Sensitive Adhesive (PSA).

Eccosorb FGM-40 is used to line cavities in which antennas operate.  These may be aircraft nacelles or caps to isolate radiation for test purposes.  It is even effective at high power levels and has a service temperature greater than most silicone rubber absorbers.
