The Role of Temperature Control during Pyrolysis of High impact Polystyrene with Decabromodiphenyl Ethane Flame Retardant in Mixed Plastics

Abstract

The effort to minimize the formation of brominated hydrocarbons has been conducted by temperaturecontrol during pyrolysis of high impact polystyrene containing decabromodiphenyl ethane (HIPS-Br) in presence of polyethyelene (PE)/polypropylene (PP)/polystyrene (PS). The products were analyzed with different gas chromatographs equipped with TCD, FID, MSD, and ECD. The controlled pyrolysis of PE/PP/PS/HIPS-Br showed that there are significant differences in the yields and composition of pyrolysis products. By controlling the temperature of pyrolysis, the formation of brominated hydrocarbons can be minimized.
