Fully sintered ferrite powders; compoundable with epoxy, plastic, paint and more. Any shape & size to reduce unwanted EMI/RF in 0.1MHz to 25GHz range.
These powders are an extension of materials designed for the heat absorbing tiles of NASA's space shuttles. Their unusual capacity for absorbing & redirecting intense heat has been further exploited by combining them with different metals. Different metals and how they are configured account for their unique properties.
This 1mm thick plate is made of epoxy and 80% powder by weight. Depending on the powder & frequency of the EM radiation, attenuation of up to 14db is possible.
