Abstract

The present invention relates to thermoplastically processable polyurethane elastomers (TPU) with tensile strengths of >35 MPa (measured in accordance with EN ISO 527-3), with shrinkages of <3% and with self-extinguishing properties based on the use of at least one flameproofing agent which can be built in, a process for their preparation and their use.
