Abstract

The present invention relates to compositions comprising at least one thermoplastic polyurethane, a first phosphorus-containing flame retardant (F1) selected from the group consisting of melamine polyphosphates and a further phosphorus-containing flame retardant (F2) selected from the group consisting of derivatives of phosphinic acid, wherein the composition is free from melamine cyanurate, and to the use of such a composition for the production of cable sheathings.
