Nonflammable high power handling EM absorbers for anechoic chambers

Our Nonflammable high power handling absorber, is a non-woven fabrics based hollow broadband microwave absorbers with fire retardant and microwave absorption impregnated.

It is mainly used in microwave anechoic chambers and can be used to shield the test equipment inside the chamber; under vertical incidence and oblique incidence conditions. It has better broadband performance; meanwhile, it has a very good scattering attenuation and isolation performance, and can be applied for all parts of the anechoic chambers.

It is a hollow broadband microwave absorber which is made of a heat resistance non-woven fabric dipped with flame retardants and microwave absorbing agents. It is mainly used in microwave anechoic chamber and covers the test equipment. Under the condition of normal incidence and oblique incidence, it has better broadband performance as well as scattering and isolation attenuation performance; it can be used in any part of the chamber.

Nonflammable high power handling absorbers
