It is produced through low-pressure polymerization with the help of the Ziegler catalyst, so high-density polyethylene is also referred to as low-pressure polyethylene. HDPE is a thermoplastic resin, which is ... WebMay 8, 2024 · The question isn't about burning HDPE but melting it at the proper temperature. (At 120 to 180°C depending on it's density, it becomes gooey. According to the source below the "extrusion" temperature range of HDPE is 176 to 260°C ― at 260°C, I guess it becomes a very viscous liquid).
