Single Layer Foams

Microwave Absorbing Foams

Laird™ brand lightweight, single layer foam absorber materials are cost efficient solutions available with assorted options to make them compliant in demanding outdoor environments.

Our single layer homogeneous material has good reflectivity at a single frequency where the thickness of the material is one-quarter the wavelength. This material is available in multiple thicknesses and loadings to cover any customer usage scenario.

Some of our material grades can be used as insertion loss absorbers to Isolate signals emitted by adjacent equipment/antenna.

Conversely, our single layer graded material will address broadband needs. For maximum performance requirements, we offer textured foam with optimum reflectivity performance.
