CA 2464989

The invention relates to foams having an apparent density of less than 100 kg/m3, in the production of which water is predominantly used as the blowing agent, and to products that contain such foams. The mentioned foams are distinguished by the fact that a large part of their cells (> 80 %) are not closed.

Mousses qui possèdent des groupes polyuréthanne et dont la densité apparente est inférieure à 100 kg/m<3>, pour la fabrication desquelles de l'eau essentiellement est utilisée en tant qu'agent gonflant, et produits qui contiennent lesdites mousses. Les mousses selon la présente invention se caractérisent en ce qu'une grande partie de leurs cellules (>80 %) n'est pas fermée.
