ECCOSORB® BSR is an ultra-thin, flexible, magnetically loaded, silicone rubber material that is electrically non-conductive. The product is particularly well suited for cavity resonance applications in very small microwave cavities typically seen in higher frequencies. When placed within a cavity ECCOSORB® BSR has proven to be very effective at dampening resonances due to the absorbers high permittivity and permeability.
Available in two types ECCOSORB® BSR-1 and ECCOSORB® BSR-2, both are engineered to reduce or eliminate surface currents, cavity resonances, coupling, and generally dampen reflections. BSR is recommended for use in high reliability aerospace and military applications, exhibiting excellent thermal cycling, outgassing, shock, and vibration characteristics. Though designed for the microwave frequency, ECCOSORB® BSR-1 at .010” thickness has been found to be quite effective at millimeter wave frequencies. It can be easily cut with a knife or die and can be held in place with an optional Pressure Sensitive Adhesive (PSA) designated as SS6M.
