Abstract
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.
