Military EMI Gaskets

EMI Gasket FabricationEMI gasket fabrication requires more than just cost-effective cutting. Precision, accuracy, and reliability are critical. In Part 2 of this series, you’ll learn how Elasto Proxy fabricates EMI gaskets made of particle-filled silicones for military and defense applications.

EMI gaskets made of particle-filled silicones are used with joints and seams in metal-to-metal interfaces. This EMI shielding conducts electricity and ensures conductivity even when there are discontinuities along metal surfaces. As we learned in Part 1 of this series, elastomeric shielding gaskets are filled with either metal- or metal-coated particles. These shielding materials combine the useful physical and chemical properties of silicone rubbers with reliable electrical conductivity and specific levels of resistance to electromagnetic interference (EMI).

In Part 2 of this series, we’ll examine how the custom fabrication of EMI gaskets supports shielding for military and defense applications. Accordingly, it’s important to note that product designers need these EMI gaskets in many different shapes and sizes. In addition to square gaskets and knife-edge profiles, examples include C, D, L, and M-shaped profiles. There are various ways to convert particle-filled silicones from sheets or rolls into specialized shapes, but water jet cutting offers advantages over methods such as die cutting.
