Reticulated Foam Absorber

Reticulated Foam Absorber


Reticulated Foam Absorber product series is a lightweight conductive carbon loaded sheet stock providing broadband loss at microwave frequencies. Reticulated Foam Absorbers are designed with a continuous gradient coating to exhibit high reflection loss and are intended to be applied to metal surfaces inside microwave cavities, housings, radomes, network enclosures, or antennae. Reticulated Foam Absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 GHz to 18 GHz.

Ordering Information

This materal is available in 610 x 610mm (24″ x 24″)  sheets only. However we can cut the sheets to shape and size as per your requirements. 

It is available with and without PSA. If you require PSA please add the suffix “-PSA” to the required part number. For example for 9.5mm thick Retuculated Foam Absorber with PSA the part number would be “MA-RF-1-PSA”.
