PU Foam Based Flat Absorbers

PU foam based flat absorbers has the advantages of light quality and good performance, which can be applied for the site near the antenna, and it can be used to reduce the side-lobe, improve the front-to-back ratio, absorb the clutter, eliminate the interference, as well provide the camouflage and concealment of the military facilities.

1. Characteristics
1) Such absorbers have a flat appearance, with black color (it can be selected as request), it is clean and soft.

2) Oxygen index ≥29% (GB/T2406-93), which belongs to flame retardant B2 level(GB8624-1997)

3) Good environmental performance, all raw materials can meet the environmental requirements, no volatile, no smell and non-toxic.
4) Installation method: Direct adhesive paste and the absorbers with self-adhesive tape can be also offered.
5) Working temperature: -60oC~90oC relative humidity: 55%±15%
     Frequency range: 1GHz~18GHz

5. Product Performance (reflectivity loss)

Note:

1) For the data above 1GHz, it is obtained by far-field RCS test method (GJB2038A-2011)

2) The performance data listed in the above table is the guaranteed data, and the measured data would be equal to or better than the guaranteed data.
