Mil / Aero Silicones

Military and Aerospace Silicones

Specialty Silicone Products Inc. (SSP) supplies high-purity platinum cure and peroxide cure silicones that meet specific application requirements.Since 1989, SSP has formulated and manufactured more than 1,000 different silicone compounds to meet the needs of clients in various industries, including aerospace and defense. 

Types of Military and Aerospace Silicones

SSP supplies premium-grade and general-purpose silicones, flurosilicones that provide fuel and chemical resistance, and silicone rubber materials that are fully-tested to specifications such as A-A-59588A and MIL-DTL-25988C. SSP also supplies AMS military compounds, flame-resistant silicones, gasket materials for high temperature and low temperature applications. 

SSP supplies the following types of military and aerospace silicones:

  • AA 59588 Silicones

    • Class 1A and 1B

    • Class 2A and 2B

    • Class 3A and 3B

  • AMS Silicones

  • MIL-DTL-25988 Fluorosilicones

Cure Systems for Military and Aerosapce Silicones

Some of SSP’s silicone elastomerics involved slight variations in pigment to match the color of customer parts. Other silicone rubber materials required full development and testing to meet customer specifications. By working closely with our partners to understand their manufacturing processes, SSP can tailor both the catalyst and cure methods to maximize efficiency, yield, and throughput.
