The flame-retardant properties in the various composites were thoroughly investigated through the limited oxygen index (LOI). The thermal properties were also explored by the thermogravimetric analyzer (TGA) and differential scanning calorimeter (DSC). The results show that the LOI values of the PET and Nylon 6 composites were obviously enhanced to 35 when small amount of CEPPA was added. Nevertheless, it was inefficient in the HDPE/PP (1:0.3) system. The optimum amount of CEPPA for PET system is about 1 ~ 2 phr based on the PET weight, and for Nylon 6 system is about 3 ~ 4 phr based on the Nylon weight.
