Eccosorb FGM is available in two thicknesses (FGM-40 at 0.040"" and FGM-125 at 0.125"") with different performance pending on targeted frequency band. The thinner FGM-40 will easily conform to contoured surfaces and both FGM-40 and FGM-125 can be bonded to metallic or non-metallic structures. Based on silicone, Eccosorb FGM 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 is used to line cavities in which antennas operate. These may be aircraft nacelles or caps to isolate radiation for test purposes. It may be applied to surfaces to improve radar performance, reduce radar cross section or backscattering.
