Abstract
The comparative analysis of a combination of primary properties of foam materials made using the different starting components and technologies was made. According to the review of the literature and analysis of the experimental data, the paper shows a significant influence the starting components and process approaches have on the properties of the materials. The comparison of material properties revealed that the properties of syntactic carbon foams are higher than those of other porous materials, including metal foams, and comply with the specification.

Summary
In today’s machine building industry, there is an urgent need to develop new, highly chemically and corrosion resistant ultra-high-temperature low-density foam materials with thermophysical properties, most significantly thermal conductivity, controllable in wide ranges. Syntactic carbon foams are promising materials for aerospace, machine building, electronics, medicine, and other industries for designing heat sinks and thermal insulation, porous materials with low density, high chemical stability, biological inertness [1]. The main purpose of these studies was to develop laboratory technologies for synthesis of thermal insulation and thermally conductive syntactic carbon foams, to prepare for designing the experimental prototype technology for synthesis of foams with a wide range of thermal conductivity and physical mechanical properties to meet the requirements of the specification according to the international agreement “Developing the technology for synthesis of products made from syntactic carbon foams with tailor-made thermophysical properties for extreme applications” [3,4,5]
