Customer Value  

Proposition:  

CHO-MUTE 9005 and 9025

elastomer based  

absorber materials are designed to offer a  

user friendly approach to the reduction of  

unwanted electromagnetic radiation from  

electronic equipment as well as minimize cavity  

to cavity cross coupling, and microwave cavity  

resonances. Comprised of a silicone elastomer  

matrix with ferrous filler material, these  

materials provide RF absorption performance  

over a broadband frequency range from 500 MHz  

to 18 GHz. The materials are offered as sheet  

stock of various thicknesses with or without  

pressure sensitive adhesive. They are flexible,  

and can be easily die-cut for use in empirical  

testing of absorption solutions. Since both  

materials have been tested and certified to the  

UL 94 V-0 flammability standard, they may be  

used in close quarters with electronic circuitry to  

reduce unwanted electromagnetic radiation by  

absorption of signals and reduction of reflections  

from metallic surfaces. A wide variety of  

fabricating techniques are available for custom  

part manufacturing.
