SSP Fluorosilicones: Advantages, Applications, Types, and Specs
- Posted By: Dominic Testo
- Category Featured, Fluorosilicones
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.
Industrial Fluorosilicones for EMI Shielding
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.

Choose Fluorosilicones from SSP
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.
