Polyurethane foam wedge absorbing material
The properties of Polyurethane foam wedge absorbing material are
similar to the one of equal height of the polyurethane foam
Pyramidal absorbing material, it has excellent performance in 100
MHZ - 110 GHZ. It is mainly used in large compact field chamber and
tapered chamber, the main advantage is to reduce the back scatter
problem of pyramidal material, get a higher static degree in quiet
zone.
Characteristics
1) Shape: rectangular pyramid, color: blue and other colors
optional
2) Flexible and bendable, the sharp top of the material will not
flap down after long term use, performance remains same within 10
years
3) Oxygen index≥29%(GB/T2406-93),flame retardant Class
B2(GB8624-1997) as well as NRL8093 Test 1, 2, 3 and UL94
4) Environmental performance is good, all raw materials conform to
the requirements of environmental protection, no volatile odor
non-toxic.
5) Working condition:normally indoor
6) Installation method: normally use a environmentally friendly
glue to adhesives on the shield, when material height under 500mm,
it can be mounted with Velcro, moreover, it can be also buckle
mounted, which is easy to replace it or rebuild the chamber.
