Syntactic Foam Buoyancy Materials
Trelleborg Emerson & Cuming, Inc manufactures several different classes of syntactic foam for undersea buoyancy applications. Blocks of the foam are typically cast in 0.5 and 1.0 cubic foot sizes, which then are used to prepare large buoyancy modules that can be readily shaped to conform to hull contours and outfitted for installation in the forward and aft free-flood areas of submarines.
Oceanographers also depend on syntactic foams to suspend instrumentation in deep ocean studies. For these applications, the syntactic foam is used in either block form or custom molded shapes for installation in manned and unmanned submersibles such as the famed Alvin and Jason vehicles that were used to discover and explore the Titanic.
