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.

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.  

•

Our specific Eccostock® foam adhesive is recommended to bond Eccosorb HR.
