Title: ELASTOMERIC COMPOSITE POLYURETHANE SKINS
Abstract:
An elastomeric composite polyurethane skin having an average flexural modulus, measured in accordance with ASTM D790-03, smaller than 35 MPa; said elastomeric composite polyurethane skins comprising a first aliphatic polyurethane layer made from a first polyurethane reaction mixture wherein said first polyurethane reaction mixture comprises at least one isocyanate compound (A1) having 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) wherein the catalyst component (C1) is substantially free of lead, and a second aromatic polyurethane layer made from a second polyurethane reaction mixture wherein said second polyurethane reaction mixture comprises at least one aromatic isocyanate compound (A2), and at least one isocyanate-reactive component (B2) characterised in that the elastomeric composite polyurethane skin has a an average areal weight of equal to or less than 750 g/m2 and the second aromatic polyurethane layer has a second average areal weight of less than 300 g/m2.
