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 • • • • Lightweight Open-cell Different thicknesses, different frequencies High free space reflectivity performance MARKETS • • • • Commercial Telecom Parabolic Antennas Security and Defense Test and Measurement SPECIFICATIONS TYPICAL PROPERTIES ECCOSORB HR Frequency Range (GHz) Max. Service Temperature °C (°F) Density kg/m³ (lb/ft³) 5 to 90 90 (194) 45 (2.8) Tensile Strength (kPA) Elongation (%) 70 170 Data for design engineer guidance only. Observed performance varies in application. Engineers are reminded to test the material in application. APPLICATIONS • • • • Lining of antenna shrouds for low side-lobe reflector antennas. Decoupling of adjacent antennas and array elements. Camouflaging and interference suppression applications. Masking of reflecting structures i.e. masts in anechoic chambers. AVAILABILITY • Standard sheets are 610mm x 610mm (24”x24”). • The material is available in 3 standard thicknesses : Eccosorb HR-10 - nominal thickness 10mm Eccosorb HR-15 - nominal thickness 15mm Eccosorb HR-25 - nominal thickness 25mm • Other sizes and customer specified configurations can be delivered upon request.

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.
