Abstract
Compositions comprising a thermoplastic elastomer, e.g., a polyurethane, a nitrogen and/or phosphorus-based, intumescent flame retardant, e.g., a polyphosphate, a non-phosphorus-based burn synergist, e.g., carbon black or a metal oxide, and an optional olefin polymer, EVA are provided. Color-stable, halogen-free, flame retardant compositions comprising a thermoplastic elastomer polymer, a phosphorus-based flame retardant, at least 3 weight percent TiO2 and a UV stabilizer are also provided.
