Nonflammable high power handing absorber

Nonflammable high power handing absorber, is a nonwoven fabrics based hollow broadband microwave absorbers with fire retardant and microwave absorption impregnated; it is mainly used in microwave anechoic chambers, and it can be used to shield the test equipments inside the chamber; under vertical incidence and oblique incidence conditions, it has better broadband performance; meanwhile, it has a good scattering attenuation and isolation performance, and it can be applied for all parts of the anechoic chambers.

Nonflammable high power handing absorbers
1. Characteristics
1) Good flame retardant characteristics, it won’t burn when it encounter the fire, it has oxygen index ≥60%, which can fully meetthe requirements of test I voltage-resistant, test II difficulty of flame ignition and propagation,test III flame-resistant test ofNavylaboratory report NRL8093(1977).
2) Excellent high power handing capacity, it can withstand the power irradiation (continuous wave) ≥6kW/sqm
3) It adopts keel mounting method, without any adhesive.
4) The absorbing performance of such absorbers is equal to or better than the PU foam absorber with same height.
5) It adopts inorganic flame retardants and microwave absorption, no volatile, no smell and non-toxic; it is stable in long-term use.
5) Working conditions:
Long-time working temperature: -50°C~120°C
Short-time working temperature: -100°C~150°C
Relative humidity: 55%±15%
