SSP fabricates EMI connector gaskets from the electrically conductive silicones that we make.
Many of our materials are independently tested and MIL-DTL-83528 QPL certified. We also offer a full certificate of analysis (COA) for every batch.
Our in-house toolroom has machinists on staff who make the dies, molds, jigs, and fixtures we use for EMI gasket fabrication.
