ABSTRACT:
A sheet or a molded object is described, which is made of a thermoplastic material comprising a polyurethane, a modified polymer and, optionally, conventional additives. This thermoplastic material thus comprises component A in the form of the thermoplastic polyurethane, the polyvinyl acetate in the form of polyvinyl acetate as well as, as flow modifier, the component C in the form of a further thermoplastic material, an elastomer-modified thermoplastic material or a rubber or combinations thereof. This material has about 10 to 35 parts by weight of polyvinyl acetate and about 1 to 50 parts by weight of component C per about 100 parts by weight of component A. The material advantageously shows an improved melt strength. When this material is calendered, no interfering sticking effects occur.
