1/ Description

AEL series absorbers are high performance multi-layer, lightweight, fl at, laminated radar absorbers. These products
are made from open cell polyurethane foam layers which are specially impregnated and laminated with fl exible
adhesives and latex. Consequently, they are fl exible and wrappable and may be pre-fi tted, cut with a sharp blade
or scissors, and bonded with contact adhesive for a strong, permanent bond. The absorber should be backed by a
refl ective surface. For optimum performance, AEMI can provide an optional conductive backing, if requested.
