Eccosorb® BSR-U

HIGH-LOSS, THIN, ELASTOMERIC MICROWAVE ABSORBER

Eccosorb BSR-U is a thin, flexible, high-loss, electrically non-conductive urethane absorber. It is designed for the frequency range from 6 GHz to mm wave. It is available in a wide range of thicknesses to suit an extremely broad range of applications including very small microwave cavities typically seen in higher frequencies. The main advantage of the polyurethane version is its ease of bonding to various substrates.

Features and Benefits

The Eccosorb® BSR-U offer a combination of functional and performance-oriented characteristics that make them a reliable choice for demanding applications.

– High mechanical strength
– Excellent abrasion resistance
– Silicone free

Examples or main applications

The Eccosorb® BSR-U are well-suited for integration into a wide range of electronic and industrial systems. Their performance and versatility make them a dependable choice across multiple sectors, supporting both high-volume manufacturing and specialized applications where reliability and efficiency are critical.
– Eccosorb BSR-U is effective in reducing surface currents, cavity resonances, coupling and to some extent specular reflections due to the absorber’s high permittivity and permeability as well as high loss values.
– It will significantly improve the operation of microwave devices by lowering the Q of cavities.
– Eccosorb BSR-U will reduce the reflections from metal structures through the absorption of surface currents.
– Applications include power amplifiers, oscillators and down/up converters.
