SSP-083 is a 60-durometer, peroxide-catalyzed, heat-cured fluorosilicone elastomer that meets MIL-DTL-25988-(C) Type 2 Class 1 Gr 60.


60-Durometer Peroxide Cure Fluorosilicone

SSP-083 is a 60-durometer (Shore A) heat-cured fluorosilicone elastomer that uses a Varox-peroxide and dicumyl-peroxide catalyst system. This fluorosilicone compound meets the requirements of both the SAE AMS 3326 and MIL-DTL-25988-(C), Type 2 Class 1 Gr 60 specifications. Because AMS3326 and MIL-R-25988C rubber requires significant testing, there is a $500 minimum order amount. Small-quantity orders may be subject to certification charges.

SAE AMS 3326 Fluorosilicones

SSP-083 elastomers meet SAE AMS 3326 and MIL-DTL-25988-(C), Type 2 Class 1 Gr 60 requirements for oil-resistant and fuel-resistant fluorosilicones. The requirements of AMS3326 are now embodied in the latest issue of AMS 3325 for aerospace materials.

MIL-DTL-25988-(C) Type 2 Class 1 Gr 60 Fluorosilicone

MIL-DTL-25988-(C) is a U.S. military specification that covers oil- and fuel-resistant fluorosilicone elastomer rubber sheets, strips, molded parts, and extruded shapes for aeronautical and aerospace applications

  • Type 2 is for molded parts (other than compression seals) sheets, strips, and extruded shapes. 
  • Class 1 is for general-purpose.
  • Gr 60 is for nominal Type A durometer hardness

Peroxide Cured Fluorosilicone Elastomers

SSP-083 fluorosilicone elastomers are peroxide-cured, a robust technique that is also cost-effective. Peroxide cure fluorosilicones are not inhibited by amines, tin compounds, latex, or urethanes, and SSP post-bakes all peroxide cured silicones to prevent bloom. SSP-083 fluorosilicones are used in aerospace and military applications, and combine broad temperature resistance with resistance to fuels, coolants, and oils.  

Form Factors and Colors for Fluorosilicone Compounds

SSP-083 fluorosilicone elastomers are supplied as ready-to-mold compounds or compression-molded sheet stock. These fluorosilicone compounds can be pigmented to meet your application requirements, but the most popular colors produced are red, blue, and black.
