Abstract
High shielding efficiencies to emissions of electromagnetic interference are achieved with molding compositions comprised of thermosetting resins and a multi-component electroconductive filler system. Compounds having a combination of at least two conductive fillers provide shielding efficiencies of 30 dB of attenuation or more to electromagnetic emissions over a frequency range of 0.5 to 1000 Mhz without adversely affecting mechanical properties and processing capabilities.
