Silicone Rolls for EMI Gaskets

SSP makes silicone rolls for EMI gaskets in standard and custom sizes. Many of our EMI shielding silicones are part of the M83528 Qualified Product List (QPL) from the Defense Logistics Agency (DLA). 

For traceability, SSP offers a full Certificate of Analysis (COA) with each batch. Compared our Made in USA materials to Parker Chomerics CHO-SEAL, Nolato Jabar, and W.L. Gore EMI shielding.

Because we’re vertically integrated, SSP can also supply you with fabricated products like EMI gaskets. Silicone rolls are ideal for automated die cutting.

How to Order Silicone Rolls for EMI Gaskets

Specialty Silicone Products (SSP) supplies EMI RFI silicones as continuous rolls both in standard and custom sizes. Roll stock is used for automated die cutting and large, non-bonded EMI gaskets and parts.

Part numbers for continuous rolls begin with the letter E and end with the letters CR. The intervening increments indicate the SSP compound and durometer (Shore A), thickness, and width.  

If you need rolls with conductive acrylic pressure-sensitive adhesive (CAPSA), please add CAPSA to the part number when ordering.

FAQ: EMI Roll Sizes

What are EMI silicone rolls used for?

EMI silicone rolls are used for die‑cutting and converting EMI/RFI shielding gaskets, pads, and custom shapes. They provide a consistent, uniform material format that converters rely on for high‑volume production and tight‑tolerance gasket fabrication.

What materials are available in EMI roll form?

SSP supplies EMI rolls in multiple conductive elastomer formulations, including nickel‑graphite, silver‑aluminum, silver‑copper, silver‑nickel, and nickel‑aluminum filled silicone and fluorosilicone. Each material offers different levels of conductivity, corrosion resistance, and environmental durability.

Do SSP’s EMI rolls meet MIL‑DTL‑83528 requirements?

Yes. SSP manufactures several EMI roll materials that meet MIL‑DTL‑83528 specifications, including QPL‑listed silver‑aluminum and silver‑copper compounds. These materials are widely used in aerospace and defense applications requiring proven EMI shielding performance.

What roll sizes are available?

Roll sizes vary by material, but SSP typically supplies EMI silicone and fluorosilicone rolls in widths and lengths suitable for die‑cutting and converting. Custom roll sizes may also be available depending on the material and production requirements.

Can SSP provide custom EMI roll formulations?

Yes. SSP can customize durometer, filler loading, thickness, color, and material properties to meet application‑specific EMI shielding, environmental, or mechanical requirements.

What industries use EMI roll materials?

EMI roll materials are used across aerospace, defense, telecommunications, medical electronics, industrial controls, and any application requiring reliable EMI/RFI shielding combined with environmental sealing.

What is the difference between silicone and fluorosilicone EMI rolls?

Silicone EMI rolls provide excellent temperature and environmental resistance, while fluorosilicone adds superior resistance to fuels, oils, and solvents. Fluorosilicone is typically selected for aerospace, defense, and harsh‑environment applications.

Are EMI rolls suitable for high‑volume converting?

Yes. SSP’s EMI rolls are engineered for consistent thickness, conductivity, and mechanical properties, making them ideal for high‑volume die‑cutting, kiss‑cutting, and automated converting processes.
