SUMFOAM® is characterized by its unique combination of different physical features: pore size in the nanometer range, low density, a stable and open-cellular structure. The 1000 times finer pore structure compared to conventional foams gives SUMFOAM® a unique status and ensures exceptional insulation performance. With the use of conventional insulating materials, a higher insulation performance is currently only realized by greater layer thicknesses. By contrast, SUMFOAM® achieves a significant reduction in thermal conductivity of up to 50% compared to common insulating materials. Thus, the energy requirement from heat losses is greatly reduced with unchanged insulation thickness. In this way, SUMFOAM® particularly contributes to the sustainable conservation of valuable resources, therefore SUMTEQ is supported by several ecological funding programs. In terms of the environmental impact of the manufacturing process, the most significant advantage is the replacement of pentane as a blowing agent by technical carbon dioxide. In contrast to pentane, this is characterized by a five times lower global warming potential. In the production of SUMFOAM®, up to 80 % CO2 equivalents are saved in the best case compared to conventional insulating materials. SUMFOAM® is grindable to rough flakes as well as down to a fine powder by keeping its full performance. This is due to the reason of its nanoporous cell structure. It leads to its good processability in different applications. In addition to the insulation performance, SUMFOAM® is also excellently suited for technical or process-oriented chemical applications due to its versatile material properties. This includes the absorption of hydrocarbon-based liquids (e.g. oil) or the use as carrier material for chemical process industries. Due to the pore size in the nanometer range, the low density and the open-cell structure, our material is able to absorb oleophilic substances in an amount of up to 6 times of its own weight, whereby the pourability is maintained. For example, plasticizers or similar liquid substances can get absorbed and mixed in dry form with other materials in the appearance of flakes or granules. This enables cross-sectoral market penetration in various industries, within SUMFOAM® enables remarkable CO2 saving potentials for the respective sector. Compared to similar competitive products, the use of SUMFOAM reduces the material requirements for all types of consumption. Better performance results in less material, better output and reduced energy expenditure. This provides specific combinations of material properties in each sector together with performance and price levels, which are unique as a new class of materials.
