Our CB Series is a cavity resonance RF absorber material designed for RFI mitigation in the 4.0 to 8.0 GHz range. Constructed from iron-loaded silicone rubber, this series is optimized for mid- to upper-microwave band applications where minimizing interference and reducing signal reflections is critical to system reliability.

With excellent magnetic loss characteristics and mechanical flexibility, the CB Series is frequently specified in enterprise networking hardware, automotive radar proximity sensors, high-speed wireless links, and lab test setups. It helps suppress unwanted emissions, improve shielding effectiveness, and maintain signal clarity in compact, complex assemblies.

The CB Series is also commonly used to line cavity walls, damp reflective surfaces near antennas, and reduce coupling in high-density RF modules. Thickness options are designed for efficient absorption without sacrificing valuable enclosure space, and optional adhesive backing supports rapid integration in manufacturing environments.
