| description | The present invention relates to a method for producing a thermoplastic polyurethane that comprises reacting an isocyanate composition at least comprising 4,4′-diisocyanatodicyclohexylmethane (H12MDI) with a polyol composition (PZ) in the presence of a catalyst composition at least comprising a bismuth-containing compound selected from bismuth (tricarboxylate) catalysts, where the carboxyl radicals independently of one another have 6 to 12 carbon atoms, to give a melt and producing pellets from the resulting melt. The present invention further relates to a thermoplastic polyurethane obtained or obtainable by the method of the invention, and also to the use for producing films, profiles, cable sheathing, and sheathing of LED strips. |
