Eccosorb® BSR-U
High-Loss, Thin, Elastomeric Microwave Absorber
HIGH-LOSS ELASTOMERIC 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.

APPLICATIONS
• 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.
AVAILABILITY
• Standard sheets are 305 mm x 305 mm (12”x12”).
• Standard thicknesses are 0.25mm (.010”), 0.50mm (.020”), 1.0mm(.040”), 1.5mm (.060”)
and 2.54mm (.100”).
• It can be supplied with a pressure sensitive adhesive designated as Eccosorb BSR -U-xx-SA ,
where the –SA suffix stands for Self-Adhesive .
• The products are also available in other sizes, thicknesses and customer specified
configurations upon request. This includes die cut and kiss cut parts to reduce installation
labor by allowing quick assembly.
