Abstract
The present invention relates to compositions comprising at least one thermoplastic polyurethane, at least one metal hydroxide, and at least one phosphorus-containing flame retardant, where the thermoplastic polyurethane is a thermoplastic polyurethane based on at least one diisocyanate and on at least one polyesterdiol, and has a weight-average molar mass in the range from 50 000 g/mol to 200 000 g/mol, measured by means of GPC. The present invention further relates to the use of compositions of this type for producing cable sheathing.
