Eccosorb HR Lightweight, Open-cell, Broadband Microwave Absorber LIGHTWEIGHT BROADBAND FOAM ABSORBER Eccosorb HR is a lightweight, flexible, flat-sheet, broadband absorber based on a reticulated (open-cell) polyurethane foam material impregnated with carbon black dispersions with controlled conductivity. Automated impregnation methods are used in order to obtain a gradient loading of the absorber. FEATURES AND BENEFITS MARKETS Lightweight Commercial Telecom Open-cell Parabolic Antennas Different thicknesses, different frequencies Security and Defense High free space reflectivity performance Test and Measurement SPECIFICATIONS TYPICAL PROPERTIES ECCOSORB HR Frequency Range (GHz) 5 to 90 Max.

The front surface should face the incident electromagnetic energy for proper performance. For optimal performance, Eccosorb HR should be bonded to a metal surface. If a metal surface is not available, the absorber can be supplied with an aluminium foil backing (ML) designated as HR-XX-ML. Our specific Eccostock foam adhesive is recommended to bond Eccosorb HR.
