Key Product Information

Manufacturing Process

FerroSorb FS-980 is manufactured from high quality, low density polyurethane foam that undergoes 15 quality assurance checks during production. The manufacturing process begins with the foam being impregnated with a proprietary, conductive carbon formula. The foam is then cut into a precise curvilinear wedge configuration by a computer controlled saw. The shaped absorber is next bonded to a precision machined ferrite tile with a tuned dielectric layer, and tested.

​Testing Process

Every piece of FerroSorb undergoes non-destructive reflectivity testing following the recommended square coax test method by IEEE-STD-1128. A vertical coaxial waveguide is used for testing across the 30 MHz to 500 MHz low frequency range. Higher frequency testing is performed using an NRL arch. This thorough testing process assures that FerroSorb FS-980 delivers consistent, repeatable performance.
