SSP makes fluorosilicone EMI shielding materials and supplies these elastomers are sheets, rolls, and ready-to-mold compounds.
Fluorosilicones are silicone-based elastomers that contain fluorine additions for improved oil and fuel resistance. Like other silicone compounds, they exhibit excellent stability over a wide range of temperatures, typically from -60° C to +200° C. Fluorosilicones also provide good compression set and resilience, and can withstand ultraviolet (UV) light, ozone, and chlorinated and aromatic hydrocarbons.
Specialty Silicone Products (SSP) supplies a complete line of fluorosilicones in a range of durometers (Shore A) and colors. Some SSP fluorosilicones contain fillers that impart or enhance certain properties. For example, SSP supplies particle-filled fluorosilicones for EMI shielding in industrial or military applications. SSP also supplies MIL-R-25988B and SMS AMS 3326 fluorosilicones.
Fluorosilicones EMI Shielding Materials from SSP
SSP’s industrial or general-purpose silicones for EMI shielding contain nickel-graphite particles. This fill material provides a reliable, cost-effective alternative to compounds that contain pure silver or silver-coated particles.

MIL-DTL-83528 Fluorosilicone EMI Shielding
For military applications, SSP supplies silver-aluminum fluorosilicones that meet the requirements of MIL-DTL-83528, Type D.
Product | Fill | Durometer (Shore A) | Tensile Strength (psi) | Elongation (%) | Typical VR (ohm/cm) | QPL? | Third-Party |
SSP2486-70* | Silver-Aluminum | 70 | 330 | 245 | .005 | Yes | 137.4 dB @ 80 MHz |
SSP550-45 | Silver-Aluminum | 45 | 185 | 350 | .002 | No | 137.8 dB @ 80 MHz |
SSP550-70 | Silver-Aluminum | 70 | 300 | 250 | .006 | No | N/A |
*SSP-2486-65 is the only QPL listed product that meets all the requirements of Type D. The other materials have not been fully tested.
SSP also supplies military and aerospace fluorosilicones that meet the requirements of MIL-R-25988 and SAE AMS 3326.
Specialty Silicone Products (SSP) manufactures fluorosilicones for EMI shielding in industrial and military products, and for military and aerospace applications that require MIL-R-25988B and SAE AMS 3326 materials. Here at our facility in Ballston Spa, New York (USA), we can manufacture 1000 ft. of materials per day – the equivalent of 600 standard 15” x 20” sheets.
Larger sheets and shorter lead times aren’t the only value that SSP adds. To learn more, contact us.
