MULTI LAYER FLAT MICROWAVE ABSORBERS

Lightweight, flexible, broadband, Multilayer PU foam based microwave absorber. Fabricated using six layers of carbon impregnated foam. FU-ML is an electrically graded flat PU foam based microwave absorber. Carbon loaded laminate polyurethane sheets. Can be readily cut on a band saw, with scissors, or a sharp knife. Available in various thicknesses from 18 mm to 120 mm and beyond. FU-ML is not waterproof and will not operate correctly when wet, since there is not washout, FU-ML will function as expected after being allowed to dry.

• Our foam absorbers are fire retardant with zero halogen means thereby avoid formation of toxic gases like HCl/HBr and poisonous gases like phosgene.
• RoHS Compliant.

• Color: As Desired, generally available in blue color.
• Typical Weight of 60 cm X 60 cm X 12 cm sheet: 2.5 kg.
• Chemical Composition: Carbon ferrite impregnated polyurethane foam.
• Maximum service temperature: 90 degree Centigrade.
• Fire Retardency: Passes NRL-8093, test 1, 2 & 3 With Zero Halogen Means.

• FU-ML has been used in reducing cross talk between adjacent antennas, shrouding antennas to improve the antenna patterns and undesired back lobes, as well as selective shadowing of parts of a target for RCS measurements.
• Shadowing of posts and supports in anechoic chambers, and as absorbing blankets for testing radar systems without harm to personnel.
• FU-ML is also effective in reducing surface current waves on metal shapes.
