Mil / Aero Silicones

Specialty Silicone Materials for Gaskets, Seals, and Insulation

Specialty Silicone Products Inc. (SSP) supplies high-purity platinum cure and peroxide cure silicones that meet your precise application requirements. Over the past 20 years, SSP has formulated and manufactured more than 1,000 different silicone compounds to meet the needs of clients in industries such as automotive, aerospace, medical equipment, satellite communications, and unmanned systems. 

Catalysts and Cure Systems

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.  

Compliant, Cost-Effective Compounds

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-R-25988. SSP also supplies AMS military compounds, flame-resistant silicones, gasket materials for high temperature and low temperature applications, and FDA compliant and USP Class VI compliant silicones.
