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).
