ECCOSORB CV is a premium quality tapered broadband microwave absorber. It is a moderately flexible urethane foam material having a front surface cut to a convoluted (eggcarton) shape. It is available in three grades, with different thicknesses, having different low frequency reflectivity limits.  Because of the rounded convolutions, and lacking sharp corners and points, ECCOSORB CV is the preferred absorber for millimeter wave frequencies and for very wide incidence angles. There is no degradation in performance at incidence angles out to 60° off-normal.

Applications:
• millimeter wave anechoic chambers
• lining the tapered walls of tapered anechoic chambers
• absorbing collars (shrouds) around the edges of high performance antennas.
