Aeroderivative turbines are derived from aircraft engines and adapted for ground-based or marine use. They’re used for power generation, marine propulsion, and to drive compressors and pumps in the oil and gas industry. Estimates vary, but the market is currently between USD $3.45 and $13.32B with compound annual growth rates (CAGR) ranging from 4.7% to 11.3% through 2035.
Aeroderivative engines, as they are sometimes called, aren’t used on jet airplanes; however, they continue to use aerospace silicones that meet AMS and A-A-59588 specifications. For gasket fabricators who want to supply GE Vernova, Siemens Energy, Rolls-Royce, Mitubishi Heavy Industries, or Kawasaki Heavy Industries, this represents a large and growing opportunity.
Specialty Silicone Products (SSP) manufactures AMS and A-A-59588 aerospace silicones at our Made in USA manufacturing facility in Ballston Spa, New York. SSP can also fabricate our materials into seals, gaskets, and O-rings using flash cutting, die cutting, or compression molding. This article explains where our spec-grade materials are used by assembly or subassembly, and by component and location.
