As pioneers in the field of ultrafine-pored polymers, we have succeeded with our material class Sumfoam in establishing the world's first scalable polymer foams with nanoporous sizes successfully in the market.

At less than 100 nanometres, Sumfoam-class foams have a pore structure that is more than a thousand times smaller than that of conventional foams. These exceptionally tiny pores and the webs that form the foam matrix open up a wealth of advantages in various areas. For example, the structure results in particularly high stability and compressive strength - and that at a simultaneously low density.

Even the smallest particle still has many millions of pores that are homogeneously distributed throughout the material. This makes it possible to grind the foam to customer specifications without affecting its performance.
