Abstract: The combination of one or more phosphorus-containing flame retardant compounds as described herein with at least one brominated flame retardant compound provides an effective flame retardant additive for thermoplastic polymers without requiring the use of antimony trioxide. Flame retardant thermoplastic compositions are therefore provided containing at least one thermoplastic polymer, at least one brominated flame retardant, and at least one phosphorus-containing flame retardant as described herein. The compositions are useful for a wide range of applications, such as for electrical and electronic applications.
