SynFoam™ is a family of structurally insulating syntactic ceramic composites combining strength, high temperature functionality and low thermal conductivity into one multifunctional material. Our ceramic syntactic foams offer good oxidation resistance (1650°C), along with low thermal conductivity (0.08W/m-K@RT) and high compressive strengths 1000-10,000 PSI). These properties put them into a class by themselves.
The nature of the syntactic foams’ closed-cell microstructure also makes them resistant to liquids and gas absorption. Powdermet offers a series of foams for high temperature applications. Silicon carbide, silicon nitride and carbon versions of the foams are available with a variety of syntactic closed-cell microstructures and varying densities (0.15-2.5g/cc), offering a variety of options for any customer and application.
SynFoam™’s unique structure is a space-filling array of hollow ceramic microballoons embedded in a ceramic matrix. These microballoons can be glass, mullite, alumina, carbon, depending upon the ceramic matrix.
SynFoam™ composites can be made from silicon carbide, carbon, zirconium carbide, zirconia, alumina, and silicon nitride.
