Web1 dic 2024 · 2 Preheat the oven to around 300 °F (149 °C). This temperature will gradually melt the plastic. However, you will need to be patient with the melting. It won’t take a blasting hot oven to melt most common plastics, such as Polypropylene, and you don't want it to be so hot that the plastic burns. [2] Web6 apr 2024 · If the melting point for a highly crystalline HDPE is 135C, then by our rule of thumb the T g would be -15C (5F). (It is actually much lower, polyethylene being one of those materials that bends some very important rules.) This is well below room temperature, requiring a cold mold to substantially suppress the crystallization process …
