EMI/RFI Gaskets

SSP fabricates EMI gaskets and RFI gaskets from the electrically conductive silicones that we make. Many of our materials are independently tested and MIL-DTL-83528 QPL certified.

We also test the EMI silicones that we make at our in-house laboratory and offer a full certificate of analysis (COA) for every batch. 

SSP even has an in-house toolroom with machinists on staff who make the molds, dies, jigs, and fixtures for the EMI/RFI gaskets we provide.

Types of EMI Gaskets

SSP fabricates die cut, flash cut, and molded EMI gaskets. We also make EMI O-rings and EMI connector gaskets.  Standard and custom EMI/RFI gaskets are available, and SSP can provide you with slash sizes for M83528 part numbers.

Die Cut EMI Gaskets

Die cut EMI gaskets are cut into specific shapes and sizes from sheets or rolls of EMI elastomers. SSP makes its own dies in-house and fabricates die cut EMI gaskets with a high degree of uniformity, even across higher volumes. Precise dimensions, parts nesting, and punched holes with specific radii are readily achievable. SSP can apply conductive pressure-sensitive adhesive (PSA) tapes for peel-and-stick parts.

Flash Cut EMI Gaskets

Flash cut EMI gaskets use CNC equipment to cut EMI elastomers into specific shapes without custom tooling. Flash cutting is ideal for rapid prototyping and short runs, and this gasket fabrication method produces extremely smooth edges with minimal loss of material. This digital manufacturing process works from your CAD file and supports flash cut EMI gaskets with a conductive PSA.

Molded EMI Gaskets

Molded EMI gaskets are produced using compression molding, a process that places a preformed rubber material into the cavity of a heated mold. SSP makes its own molds in-house and produces compression-molded EMI gaskets using the same materials that we supply as sheets, rolls, and extrusions. For large picture-frame style gaskets, molding can increase material yields and reduce material waste.

Custom Molded EMI Gaskets

SSP-5259 Nickel Aluminum Shielding Silicone


SSP502-65 supports thinner, smaller, and lighter-weight designs. This EMI RFI elastomer also offers performance levels that are comparable to shielding silicones with silver-coated particles.
