Product Details

Semi Open PU Foam based broadband type embedded pyramidal microwave absorbers. Specially formulated coatings for better ageing characteristics. Light weight, flexible and easy to cut. Polyurethane foam sheet dipped in absorbing slurry providing desired electrical grading. Standard size is 600 mm X 600 mm. Custom tailored sizes can also be supplied. Thicknesses are 45mm, 35mm, 30mm, 25mm, 15mm, 12.5mm and 10 mm (FAS-45, FAS-35, FAS-30, FAS-25, FAS-15, FAS-12.5 and FAS-10). Larger thickness can be produced to suit low frequency applications. Colored surface should face the incident radiation. The back surface (black) should be close to the metallic surface to achieve best performance. Provides better wider angle performance than multilayer flat absorber.

FEATURES:

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.

MATERIAL PROPERTIES:

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.

AREAS OF APPLICATION:

FAS 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.
FAS is also effective in reducing surface current waves on metal shapes.
