Absorber is a complete range of high performance wedge microwave absorbers having approximated same properties at grazing incidences as our FU-SE Series-Pyramidal Microwave Absorbers at near normal incidences. Constructed using low density, flexible foam, impregnated with a carbon black, ferrite formulation to achieve the desired electrical performance. At higher angle of incidences backscatter is significantly reduced. Available in wide range of thickness and absorbencies. Variety of thickness gives the chamber designer the opportunity to choose grades appropriate for specific frequencies and incidence angles.
FEATURES
- Absorption over a wide frequency range.
- Long product life.
- High performance, up to – 45 dB reflection loss at grazing incidences.
- These absorbers are supplied with a fire retardant finish.
- RoHS Compliant.
MATERIAL PROPERTIES
Color: As Desired, generally available in blue color.
Dimensions: 60 cm X 60 cm.
Chemical Composition: Carbon ferrite impregnated polyurethane foam
Maximum service temperature: 90 degree Centigrade
Power handling capacity: 0.5 Watt/Cm2
Fire Retardency: Passes NRL-8093, USA test 1, 2 & 3 With Zero Halogen Means.
Our foam absorbers are fire retardant with zero halogen means thereby avoid formation of toxic gases like HCl / HBr and poisonous gases like phosgene.
