Abstract
Foam assisted forming technology introduces new exciting
opportunities to develop totally new types of sustainable
wood fibre products. The technology allows highly porous
and thick structures to be produced from fibres and it
enables the exploitation of new raw material combinations
extending the raw material base. Porous fibre structures
can be made of any fibre or fibrous particle blends with
or without additives that possess adequate level of
bonding or adhesion in wet and dry state.
Foam forming technology utilises small air bubbles
containing aqueous foam as a process fluid. In the foam
forming process fibres, water and foaming agent are
mechanically mixed and the aqueous fibre-containing foam
is generated with air content between 50-70%. The air
bubbles effectively prevent flocculation of fibres.
Highly porous, non-paper like materials can be produced
by using small vacuums in the drainage phase and by using
non-contact drying methods to prevent the collapse of the
fibre network. This paper highlights VTT Technical
Research Centre of Finland's foam forming research, shows
research results and presents end product examples.
