The innovative SUMTEQ-technology enables a practicable and efficient production of polymer foams with pore sizes below one micrometer (nano). Due to the resulting excellent insulation properties they are of great relevance for economy, society and politics.
It is the aim of our company to make SUMTEQ-technology and SUMFOAM ready for the market and to establish our products successfully together with our partners in the relevant field of applications.
SUMFOAM - Features
SUMFOAM - Technology
SUMFOAM is the first foamed polymer material with a homogeneous nanostructure, which can be produced under industrial conditions.
The diameter of the foam pores is in the submicron range and the foam consists of more than 90% air. The foam pores with sizes of a few hundred nanometers are smaller than the tiniest bacteria. This means that one liter of foam has a surface area equal to the size of 10 football pitches. The number of pores of more than a trillion comes close to the number of sand grains of all beaches in the world.
As a consequence of having this ultrafine structure SUMFOAM combines unique material properties. It is especially the Knudsen-Effect that significantly improves the insulation properties creating a huge leap in energy efficiency compared to conventional insulating materials with the positive effect of a sustainable conservation of resources.
In addition SUMFOAM is characterized by an extremely high mechanical stability at a relatively low density and so it can be easily formed, shaped without producing dust and is also extremly hydrophpobic.. As the foaming process is exclusively performed with climate-friendly CO2 and the product can be recycled 100%, a huge ecological benefit can be achieved.
SUMFOAM has the potential for completely new and sustainable material solutions in the field of many diverse applications.
