Abstract

L'invention concerne un procédé de préparation de mousse présentant des groupes uréthanne, durcissant à froid, flexible, par réaction de polyéthers présentant au moins deux groupes hydroxy, de poids moléculaire 400-10 000, dans lesquels au moins 10 % des groupes hydroxy présents sont des groupes hydroxy primaires, avec un mélange de diisocyanates. Le mélange de diisocyanates de diphénylméthane et de polyphényl-polyméthylène-polyisocyanates oligomères contient 60-90 % en poids, préférence 65-80 % en poids, de 4,4'-diphénylméthanediisocyanate, et 3-30% en poids, de préférence 10-30% en poids, de 2,4'-diphénylméthane-diisocyanate. Rembourrage.
