The high-performance material SUMFOAM®
- Acrylic copolymer as starting material
- Open-cell, flexibly modifiable nanostructure (< 50 nm)
- High thermal insulation performance < 23 mW/mK
- Density depending on pore size between 50 – 100 g/l
- High pressure stability > 0.7 Mpa
- High absorption capacity > 7 kg/kg (e.g. oil)
- BET Surface area > 100 m²/g
- Extremely hydrophobic surface
- Temperature resistance up to 80 °C
- Cost-effective and scalable foaming process of the polymer
- Form flexible design (granulate, flake, powder, panel, shaped part)
- 100% foamed with climate-neutral blowing agent
The innovative SUMTEQ technology enables for the first time a practicable, scalable and efficient production of polymer nanofoams, in which there is enormous economic, social and political interest, particularly due to the excellent insulating properties.
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 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.
