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.

INSTRUCTIONS FOR USE
•
Eccosorb BSR is designed to function directly in front of a metallic surface.
•
For applications where the service temperature exceeds 121°C (250°F), the material can be
bonded to most substrates by using an RTV silicone based adhesive in conjunction with a
suitable primer.
•
Eccosorb BSR can be readily cut with a sharp knife and template.
It is a very flexible material and conforms to contoured surfaces.
