More Information
Summary:Composites having a polymer or natural leather skin layer and a polyurethane foam layer are made in a molding process. The polyurethane foam layer is made from a foam formulation that includes certain polyester polyols. The presence of the polyester polyol improves flow characteristics of the foam formulation. The foam so produced has unexpectedly low quantities of VOCs. L'invention concerne des composites, comportant une couche de peau en cuir naturel ou en polymère et une couche de mousse de polyuréthane, qui sont fabriqués lors d'un procédé de moulage. La couche de mousse de polyuréthane est fabriquée à partir d'une formulation de mousse qui comprend certains polyols de polyester. La présence du polyol de polyester améliore les caractéristiques d'écoulement de la formulation de mousse. La mousse ainsi produite présente des quantités étonnamment faibles de COV.
