SSP-100 is a 70-durometer, heat-cured fluorosilicone elastomer that meets MIL-DTL-25988C, Type 1 and 2, Class 2, Grade 70 requirements.


70-Durometer Peroxide Cure Fluorosilicone

SSP-100 is a 70-durometer (Shore A) heat-cured fluorosilicone elastomer that uses a Varox-peroxide and dicumyl-peroxide catalyst system. This fluorosilicone compound meets the requirements of the MIL-DTL-25988C, Type 1 and 2, Class 2, Grade 70 specification. Because MIL-DTL-25988C rubber requires significant testing, there is a $500 minimum order amount. Small-quantity orders may be subject to certification charges.

MIL-DTL-25988C, Type 1 and 2, Class 2, Grade 70 Fluorosilicones

SSP-100 elastomers meet MIL-DTL-25988C, Type 1 and 2, Class 2, Grade 70 requirements for oil-resistant and fuel-resistant fluorosilicones. According to this U.S. military specification, Type 2 fluorosilicone elastomers are for molded parts (other than O-rings), sheets, strips, and extruded shapes. Class 1 fluorosilicones are general-purpose elastomers. Class 2 fluorosilicones add high-strength. Grade 70 indicates that the rubber has a nominal 70-durometer hardness.

Peroxide Cured Fluorosilicone Elastomers

SSP-100 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-100 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-100 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.
