About sumfoam
Sumfoam is an innovative polymer foam with a pore size of less than 100 nanometers. It is not only a product, but a new class of materials, since for the first time it has been possible to foam polymers with a nanoporous structure using a scalable process.
The small pore size gives Sumfoam its extraordinary thermal insulation performance and enables application-specific grinding to coarse flakes or even to a fine powder with a particle size of less than 50 µm. All this while maintaining full performance.

We foam our polymer with a disruptive process using a climate-neutral blowing agent. In the course of the expansion process, the volume increases by a factor of about 10 to 20, with the polymer developing a homogeneous and open structure with a pore size in the nanometer range. This corresponds to a pore structure that is 1000 times finer than that of conventional foams.

Ökologischer Nutzen
In all areas the topic sustainability plays a priority role. SUMTEQ GmbH is active in over thirty business areas and develops individual recycling concepts.
Ecological benefit
We have already received funding from Deutsche Bundesstiftung Umwelt by two project-specific programs, were selected among the top three companies at the StartGreen Award 2019 and reached the finals in the ISC3 Innovation Challenge 2020 for sustainable chemistry.
We are permanently working on the optimization of our CO2 footprint and have received funding to reach the next scaling level as part of the BMU’s environmental innovation program.
