Broadband EPP Microwave Absorber Foam Anechoic Chamber Absorber Material

Broadband EPP Microwave Absorbing Cones for Anechoic Chambers

Broadband EPP microwave absorbing cones are engineered to create highly controlled electromagnetic environments for precision RF testing and antenna measurement applications. Manufactured using advanced expanded polypropylene technology, this absorber combines lightweight structure with stable electromagnetic performance across a wide frequency spectrum.

Unlike traditional foam absorbers, the closed-cell material structure effectively prevents moisture penetration and material degradation, ensuring long-term reliability even under demanding laboratory conditions. The optimized cone geometry enhances multi-reflection attenuation, significantly reducing unwanted signal reflections inside anechoic chambers.

Main features

(1) Closed hole material, moisture-proof and mildew-proof, no powder drop, strong weather resistance. Long service life

(2) High mechanical strength, through the patented structure design to achieve ultra-wide band strong absorption, long-term electrical performance stability

(3) the material itself is flame retardant, the flame retardant performance is stable, long-term use of flame retardant does not exude

(4) Meet the requirements of RoHS environmental protection directive, and install by mechanical connection. The installation is environmentally friendly and pollution-free.

(5) Customized to achieve beautiful anechoic chamber. Comfortable and bright

Application fields

Microwave anechoic chamber, far field, near field, compact field, etc.
