Product Description
The EMC Absorber is a high-performance RF absorbing material tailored for use in anechoic chambers, EMC test sites, and shielding rooms. It features a truncated pyramidal shape, delivering wideband absorption with low reflectivity. Made from carbon-loaded polyurethane foam, it is lightweight, flame-retardant, and easy to install, making it suitable for both large facilities and compact setups.
This absorber effectively solves challenges such as limited chamber space, high reflectivity, and insufficient frequency coverage. Its truncated design helps reduce the overall height required in low-ceiling environments while maintaining excellent electromagnetic attenuation across a broad spectrum.
Compared to conventional absorbers, our EMC Absorber offers superior performance-to-height ratio, enhanced safety features, and greater installation flexibility. It’s particularly well-suited for hybrid test systems where both performance and space efficiency are critical.
