Abstract
A composite body is provided that includes a rigid polyurethane foam shell and an elastomeric polyurethane layer disposed over the rigid polyurethane foam shell. The rigid polyurethane foam shell defines a cavity within the composite body. The rigid polyurethane foam shell has a closed cell content of at least 70% and comprises the reaction product of a first isocyanate component and a first isocyanate-reactive component in the presence of a blowing agent. The elastomeric polyurethane layer is disposed over the polyurethane foam shell. The elastomeric polyurethane layer comprises the reaction product of a second isocyanate component and a second isocyanate-reactive component. A method of forming the composite body includes the step of molding the rigid polyurethane foam shell, demolding the rigid polyurethane foam shell from the mold, and applying an elastomeric polyurethane composition upon the rigid polyurethane foam shell after demolding to form the elastomeric polyurethane layer.
