Study on the Conversion Technology of Waste Polyethylene Plastic to Polyethylene Wax

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 104–144°C. The penetration degree is 0.1–42.4 mm; the yield of PE wax is over 90%.
