Eccosorb® BSR
High-Loss, Thin, Elastomeric Microwave Absorber
HIGH-LOSS ELASTOMERIC ABSORBER
Eccosorb BSR is a thin, flexible, high-loss, electrically non-conductive silicone absorber.
It is designed for the frequency range from 6 GHz to mm wave. It has low outgassing
properties and high temperature resistance.
FEATURES AND BENEFITS
• High thermal stability
• Electrically non-conductive
• High magnetic loss
MARKETS
• Commercial Telecom
• Security and Defense
• Automotive and Industrial Electronics

Data for design engineer guidance only. Observed performance varies in application.
Engineers are reminded to test the material in application.
* Outgassing data per ASTM E595-07; criteria for acceptability is 1.00% TML and 0.10% CVCM.
APPLICATIONS
• Eccosorb BSR is engineered to reduce or eliminate surface currents, cavity resonance,
coupling, and generally dampen reflections. It will significantly improve the operation of
microwave devices by lowering the Q of cavities.
• Eccosorb BSR is recommended for use in high reliability aerospace, military, and space
applications, exhibiting excellent thermal cycling, shock and vibration absorption
characteristics.
• Some other applications include power amplifiers, oscillators and down/up converters.
AVAILABILITY
• Standard sheets are 305 x 305mm (12”x12”).
• Standard thicknesses are 0.25mm (0.010”), 0.50mm (0.020”), 1.0mm (0.040”), 1.5mm
(0.060”) and 2.54mm (0.100”).
• For most applications Eccosorb BSR can be supplied with a Pressure Sensitive Adhesive.
• Eccosorb BSR is 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.
