Abstract
Appareil pour la fabrication de mousses de forme stable et de faible masse volumique formées de résine urée/formaldéhyde durcie. Il comprend une tête mélangeuse centrifuge, pouvant prendre la forme d'un rotor avec au moins une pale, fixée radialement sur un arbre d'entraînement central, et éventuellement perforée pour améliorer l'action de brassage. Application notamment aux mousses légères, de masse volumique non supérieure à 20 kg/m**3.
