Abstract

L'invention concerne la préparation d'une mousse en polyuréthanne d'ester reposant sur la réaction d'un mélange d'au moins un polyol de polyester avec au moins un isocyanate et au moins un agent de surface de silicone en présence d'un agent d'expansion, tel que l'eau, et d'autres additifs, tels que des catalyseurs. La mousse durcie est traitée chimiquement dans une solution caustique et, puis, elle est feutrée (comprimée sous l'effet de la chaleur et de la pression) pour former une mousse en polyuréthanne d'ester hydrophile possédant un taux d'absorption d'eau d'au moins 30 livres d'eau par pied carré par minute (1,44 kPa/min). La mousse présente également une capacité de rétention d'eau et une hydrorésistance meilleures que la cellulose.
