Full Product Description
Parker Chomerics CHO-MUTE 9009 is an elastomer-based absorber material 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 carbon filler material, this material provides RF absorption performance at a high frequency range. CHO-MUTE 9009 is capable of providing 50 dB/cm of absorption at 77 GHz, a standard frequency used in the automotive industry. This material is offered as sheet stock of various thicknesses with or without pressure sensitive adhesive. This material is flexible, and can be easily cut and converted for use in empirical testing of absorption solutions.
CHO-MUTE 9009 may be used in close quarters with electronic circuitry to reduce unwanted electromagnetic radiation by ¿sorption of signals and reduction of reflections from metallic surfaces. A wide variety of fabricating techniques are available for custom part manufacturing.
