ABSTRACT:
The present invention relates to low-halogen-content, thermoplastically-processible polyurethane elastomers (TPU), to which are added antimony trioxide, chlorinated and/or brominated aromatic compounds having a specified halogen content, aluminum hydroxide having a specified particle size, phosphoric acid tris-ester, and, optionally, quaternary tetra-alkyl ammonium salts. These additives impart an unexpectedly favorable combination of electrical surface properties, flameproof behavior and abrasion resistance.
