Laird Performance Materials Eccosorb™ RF-RET Broadband Foam Absorbers are lightweight open-celled reticulated foam absorbers that offer 20dB performance ratings. The defined cell structure is formed by the reticulated urethane backbone, and when treated with a lossy coating, the material is extremely lightweight, providing broadband reflectivity reduction. RF-RET absorbers are used for antenna reflection reduction where broadband reduction coupled with a lightweight design is required. Laird Performance Materials Eccosorb RF-RET Broadband Foam Absorbers are useful in anechoic chambers to cover pedestals and equipment.
