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

Eccosorb® HR INSTRUCTIONS FOR USE • As the material is a gradient loaded absorber, the back side of the absorber is marked and this side should be bonded to the surface. 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.
