Flame-retarded polymer formulations are mainly used in long-term applications whereas antioxidants, light stabilizers, and other additives provide the requested lifetime of plastic materials. However, many flame retardants influence the oxidative and photooxidative stability of polymers often in a negative way resulting in early failure and loss in value. On the other side, insufficient (photo)oxidative stability of the flame retardant itself may reduce the flame retardance performance over time. Therefore, depending on the type of flame retardant used, the polymer substrate and the intended application adjusted stabilizer systems have to be selected or developed.In this chapter, challenges of the stabilization of flame-retarded polymers are analyzed with regard to the components and mutual interactions with focus on "green" flame retardants. Processing and long-term thermal stabilization of flame-retarded polymers are discussed and strategies of improving the light sta bility of flame-retarded polymers are provided. Additionally, the specific requirements of the stabilization of nanocomposites as potential flame-retardant components are covered.
