The process of converting polyethylene plastic waste to polyethylene wax is studied in this paper. The effect of the reaction conditions-including pyrolysis temperature, pyrolysis time, and the content of the additive-on the yield and quality of the PE wax-such as penetration degree and melting point-are discussed. The PE wax obtained has a melting point of 104-144degreesC. The penetration degree is 0.1-42.4 mm; the yield of PE wax is over 90%.
