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
Claims10
A halogen-free flame-retardant composition comprising:
- (a) 10 to 89 weight percent, based on the total weight of the composition, of a continuous resin phase comprising a thermoplastic polyurethane;
- (b) 1 to 10 weight percent, based on the total weight of the composition, of an aromatic organic phosphate flame retardant having a melting point of at least 50° C.;
- and
- (c) 10 to 89 weight percent, based on the total weight of the composition, of an inorganic hydrate flame retardant;
- the composition comprising no greater than 10 weight percent, based on the total weight of the composition, of a liquid organic flame retardant having a melting point of 25° C. or lower.
