Abstract: The invention relates to a method for the combined processing of at least two polymer melts selected from the group consisting of (M1), (M2) and (M3), wherein (M1) is a polymer melt comprising a terephthalate polyester (A1), (M2) is a polymer melt comprising a copolyester (A2) on the basis of terephthalic acid, at least one aliphatic, ?-dicarboxylic acid and at least one aliphatic 1,?-diol, and (M3) is a polymer melt 0 comprising a copolyester (A3) on the basis of terephthalic acid, at least one polytetramethylene glycol and at least one aliphatic 1,?-diol. The method comprises the alternating processing of the at least two polymer melts into at least one product selected from the group consisting of pellets (P1), fibers (P2), expanded particles (P3), preforms (P4) and articles (P5).

Abstract: A composite element in the furniture sector, preferably furniture doors and furniture carcasses, comprises (i) laminated or unlaminated materials based on wood, wood boards or particle boards and/or wood-like materials, preferably based on wood boards or particle boards, and (ii) thermoplastic polyurethane. Processes for the production of these composite elements and in particular furniture carcasses or doors comprising the novel composite elements are furthermore described. In particular, film hinges, preferably for furniture construction, for example for furniture carcasses, drawers or door frames, in particular for furniture carcasses based on thermoplastic polyurethanes are described.
