More Information
Summary:A reactive polyurethane foam-forming composition including (I) an isocyanate-containing material; and (II) a polyol-containing admixture of: (a) at least one autocatalytic polyol; (b) at least one grafted polyol; (c) at least one reactive polyether polyol; (d) at least one reactive catalyst; (e) at least one surfactant; and (f) water; and a process for making the above foam-forming composition. L'invention concerne une composition réactive de formation de mousse de polyuréthane comprenant (I) un matériau contenant de l'isocyanate ; et (II) un mélange contenant un polyol constitué par : (a) au moins un polyol autocatalytique ; (b) au moins un polyol greffé ; (c) au moins un polyéther-polyol réactif ; (d) au moins un catalyseur réactif ; (e) au moins un tensioactif ; et (f) de l'eau ; et un procédé de préparation de la composition de formation de mousse ci-dessus.
