Versatile
The innovative technology allows a high degree of flexibility in regard to form and shape as well as dust-free processing of SUMFOAM.

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 and shaped without producing dust. 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.
