"The trimmings are shredded into flakes before being wetted with a polyurethane adhesive,then blended in a mixer and discharged into a mould. Since the loose flakes have a significantly lower bulk density than the finished block, the flakes are compressed inside the mould. Rebonded foam is subsequently formed by adding hot steam and pressure
. "
Broad density range
"The density of the finished blocks ranges between about 80 and 120 kg/m3. Block densities of up to 500 kg/m3 are feasible with a suitable flake preselection and special equipment

Advantages:
Production of a new, profitable high-quality product
Environmentally compatible recycling technology
Almost full re-use of all trimmings obtained in slabstock manufacturing
Homogeneous integration of PU flakes into the foam cell structure
