Abstract
Halogen-free, thermoplastic polyurethane-based compositions having good mechanical and flame-retardant properties are provided. The compositions include flame-retardant aromatic organic phosphate compounds that do not exhibit migration in molded products, such as cable and wire jacketing and insulation. The compositions include a continuous resin phase comprising a thermoplastic polyurethane elastomer, at least one aromatic organic phosphate flame retardant having a melting point of at least 50.
