Microwave absorbers

Absorbent materials are used for EMI isolation and RFI absorption. These are available in many different materials to achieve absorption from 5 MHz up to 110 GHz.

Different materials that can contain doped (filled) are for example urethane, silicone, nitrile, neoprene, thermoplastic and foam. There are many ways to manufacture absorbers to get the desired properties such as single or multiple frequencies. We also offer absorbent shrink tubing and extruded cable absorber (eliminates grease traps).
