Eccosorb® MCS

High-Loss, Thin, Elastomeric Microwave Absorber

HIGH-LOSS ELASTOMERIC ABSORBER

Eccosorb MCS is a thin, flexible, high-loss, magnetically loaded, electrically non-conductive

silicone rubber sheet. It is designed for the frequency range from 800 MHz to 18 GHz.

The material is impervious to moisture and can be subjected to high altitudes with no adverse

effects. Being a silicone based absorber, it has low out-gassing properties for space

applications.

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

resonances due to the absorbers high permittivity and permeability as well as high loss

values, which in turn reduces the overall VSWR.
