MIL-DTL-83528 Type D
CHO-SEAL 1287 and CHO-SEAL 1298 alternative. SSP2486-70 is a 70-durometer silver-aluminum EMI shielding fluorosilicone. MIL-DTL-83528 Type D. QPL listed.
Fluorosilicone conductive elastomers for fuel and solvent EMI gasket applications, including jet fuels and de-icing fluids amongst other harsh fluids.
Choose sheets, rolls, moldable compounds, extrusions, EMI O-rings, or EMI gaskets.
SSP’s fuel and solvent resistant EMI fluorosilicones include a QPL certified MIL-DTL-83528, Type D elastomer and nickel-graphite materials in 50, 60, and 80 durometer (Shore A). There are also two silver-aluminum fluorosilicones, including a passivated product. Passivation increases the corrosion resistance of the electrically conductive metal particles.

SSP502F-50 is a 50-durometer fluorosilicone that’s filled with nickel-coated graphite particles. It’s electrically conductive and combines reliable environmental sealing with superior shielding against electromagnetic interference (EMI) and radio frequency interference (RFI).
SSP502F-60 is a 60-durometer fluorosilicone that’s filled with nickel-coated graphite particles. It is dark gray in color, has a thermal stability range of –55° C to 200° C.
SSP502F-80 is ideal for thinner, lighter-weight solutions and has a typical shielding effectiveness of 113 dB at 20 MHz to 10 GHz (E-Field).
SSP550-45 is a 45-durometer, electrically-conductive, silver-aluminum shielding fluorosilicone. Find out if this silicone compound is right for your specific EMI RFI shielding application.
SSP550-70 Passivated is a 70-durometer, electrically-conductive, silver-aluminum shielding fluorosilicone that is designed to meet MIL-DTL-83528C Type D. Find out if this fluorosilicone compound is right for your specific EMI RFI shielding application.
SSP also offers these other types of EMII/RFI shielding materials. We also fabricate EMI gaskets and EMI O-rings from the elastomers we make.
Fuel‑ and solvent‑resistant EMI materials use fluorosilicone binders that withstand exposure to fuels, oils, hydraulic fluids, solvents, and other aggressive chemicals. These materials maintain their mechanical properties and electrical conductivity even in harsh chemical environments.
Fluorosilicone provides the same temperature stability and flexibility as silicone but adds exceptional resistance to fuels and solvents. This makes it ideal for aerospace, defense, automotive, and industrial systems where chemical exposure is unavoidable.
Yes. SSP’s fluorosilicone EMI materials are engineered to deliver reliable shielding effectiveness across a wide frequency range while maintaining chemical resistance and long‑term durability.
SSP offers fluorosilicone EMI materials with nickel‑graphite, silver‑aluminum, silver‑copper, silver‑nickel, and nickel‑aluminum fillers. Each filler system provides different levels of conductivity, corrosion resistance, and galvanic compatibility.
Several fluorosilicone EMI materials can meet or exceed MIL‑DTL‑83528 performance requirements depending on the filler system. SSP can help determine the best option for applications requiring both chemical resistance and MIL‑spec compliance.
Yes. SSP supplies fuel‑ and solvent‑resistant EMI materials in sheet form, roll form, and moldable compounds for compression, transfer, and injection molding.
These materials are ideal for aerospace fuel systems, defense electronics, avionics, automotive powertrains, industrial equipment, and any environment where EMI gaskets may be exposed to fuels, oils, or solvents.
Absolutely. SSP can tailor durometer, filler loading, thickness, color, and cure characteristics to meet specific electrical, mechanical, and chemical‑resistance requirements.
