SSP083
SSP083 is a 60-durometer, peroxide-catalyzed, heat-cured fluorosilicone elastomer that meets SAE AMS 3326 and MIL-DTL-25988-(C), Type 2 Class 1 Gr 60 requirements. Find out if this silicone rubber is right for your application.
SSP makes MIL-DTL-25988, Type 2, Class 1 and 2 fluorosilicones. Choose sheets, rolls, extrusions, or ready-to-mold compounds.
MIL-DTL-25988 is a U.S. military specification that supercedes MIL-R-25988. Older prints may reference MIL-R-25988, or spec AMS 25988.
Concerned about traceability? SSP offers a full Certificate of Analysis (COA) for every batch of material that we make.
MIL-DTL-25988 is a U.S. military detail specification that supercedes MIL-R-25988. It divides compliant fluorosilicones into Type 1 materials for O-Rings and Type 2 materials for molded parts, sheets, strips, and extruded shapes. Within each Type, there are two different classes. Class 1 compounds are for general-purpose use, and Class 2 materials are higher-strength elastomers.
SSP makes Type 1, Class 1 and 2 MIL-DTL-25988 fluorosilicones and supplies them as ready-to-mold compounds, continuous rolls, sheet materials, and extrusions. The table below lists our products. All fluorosilicones are peroxide-catalyzed and heat-cured. For traceability, SSP offers a full certificate of analysis (COA) with every batch.

MIL-DTL-25988 Aircraft Fluorosilicones and Aviation Fluorosilicones
MIL-DTL-25988 is a U.S. military detail (DTL) specification that covers fluorosilicones for aircraft and aviation applications. With their fluorine additions, these silicone elastomers resist petroleum-based fuels and oils, solvents, and harsh chemicals.
MIL-DTL-25988 fluorosilicones also withstand a wide range of temperatures and maintain their tear and tensile strength when immersed in jet fuel. These fuel-resistant materials can withstand repeated flexing without stress cracking and remain flexible and rubbery.
The MIL-DTL-25988 specification divides compliant fluorosilicones into different types, classes, and grades.
