ABSTRACT
Conductive elastomers have been used successfully in electromagnetic interference (EMI) shielding applications mainly focusing on EMI gasketing. The primary function of elastomeric gaskets is to provide sufficient conductivity across the enclosuregasket-lid junction or other gasketing joints, and to act as a seal or barrier to prevent fluid or moisture intrusion into the shielded components. Partly because of their high costs, conductive elastomers were initially limited to military and aero space applications. With the advancements in digital electronics and miniaturization of electronic components, however, the increasing electromagnetic compatibility (EMC) requirements have promoted demands for cost-effective elastomeric materials in commercial applications.
