Abstract
L'invention concerne un procédé de fabrication de polyuréthanne et de mousses de polyisocyanurate consistant à introduire au moins un agent d'expansion et un composant polyol dans un agitateur-mélangeur permanent en ligne, dans lequel, l'agent d'expansion, au moins un, et le composant polyol sont introduits, en permanence, dans des flux séparés coulant à des débits prédéterminés choisis afin d'apporter la proportion souhaitée d'agent d'expansion au composant polyol à l'intérieur de l'agitateur-mélangeur permanent en ligne.
