Melting Hdpe – Learning for Kids

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).
