Abstract: An elastomeric composite polyurethane skin having an average flexural modulus, measured in accordance with ASTM D790-03, smaller than 35 MPa is disclosed. The elastomeric composite polyurethane skin includes a first aliphatic polyurethane layer made from a first polyurethane reaction mixture having at least one isocyanate compound with at least two NCO-groups which are not directly attached to an aromatic group, at least one isocyanate-reactive component (B1), and at least one catalyst component (C1) substantially free of lead, and a second aromatic polyurethane layer made from a second polyurethane reaction mixture having at least one aromatic isocyanate compound (A2), and at least one isocyanate-reactive component (B2).

Abstract: The present invention relates to a method for manufacturing a flexible skin which has at least one insert adhered thereto. In a first step, the skin is molded on a mold surface. In order to adhere the insert to the skin, an opening is first made in the skin giving access to the back face of the insert. The insert is positioned with its back face against the front face of the skin and an adhering layer is provided which is adhesively connected to the back face of the skin layer which surrounds the opening in the skin layer and, through this opening, to the back face of the insert. The adhering layer is preferably produced by applying a layer of a hardenable material, in particular a curable polyurethane composition. Since the back face of the insert engages the front side of the skin penetration of hardenable material to the front face of the insert is avoided.
