Halogen-free flame retardant compositions comprising thermoplastic elastomers, which exhibit flame retardance and low-smoke emission. The flame retardant compositions comprise a) one or more thermoplastic elastomers, and b) from at or about 18 to at or about 50 weight percent, the weight percentage being based on the total weight of the flame retardant composition, of a flame retardant mixture comprising: b1 ) at least one flame retardant comprising a phosphinate, diphosphinate and/or polymers thereof, b2) a phosphorous-containing amino composition; and b3) a zeolite.
