The thermal stability and degradation kinetics of TV housing plastic and brominated flame retardants were studied by means of thermogravimetry. The effects of the treatment temperature on the removal rate of Br were investigated using a tube furnace reactor under isothermal and vacuum conditions. The results showed that the weight loss of TV housing plastic was divided into two stages: the thermal degradation of brominated flame retardants mainly occurred at 290A degrees-350A degrees C, and the degradation of the high-impact polystyrene resin mainly occurred at 350A degrees-455A degrees C. Nearly 90% of Br can be removed from TV housing plastic when the treatment temperature exceeds 280A degrees C.
