Abstract
Multi-layer moulding, containing a body part and a surface layer which at least partly covers the body part, which body part contains a cross-linked elastomer composition and which surface layer contains a thermoplastic elastomer, in which the surface layer of the multi-layer moulding, in a weather resistance test according to DIN 75202, in which the surface layer is continuously exposed for at most 100 hours to light from a xenon light source, which light source is provided with a borosilicate “S” inner filter and a soda lime outer filter, at a relative humidity of 30%, with an intensity of 1.40 W/m2 at 420 nanometres on the surface of the moulding, a black standard temperature of 100° C., in a space with a temperature of 66° C., develops a colour deviation with a ΔE of at most 3.0, measured according to ASTM D 1925.
