Abstract

In the method according to the invention, a layer of polyurethane elastomer for obtaining a polyurethane skin (5) is produced, in a first step, against a mould surface (1). In a second step, a reaction mixture for obtaining a polyurethane foam layer (6) is applied against this polyurethane skin (5). In a third step, a suitable polyurethane or polyisocyanurate reaction mixture for obtaining a rigid synthetic carrier (8) is applied against the polyurethane foam layer (6). In this way, a synthetic trim part is obtained which is easier to recycle. This method can moreover also be performed easier.
