| Nominal °C / °F | Range °C / °F | |
|---|---|---|
| Oven Temperature – Actual air in oven | 300 °C / 570 °F | 280 – 315 °C / 540 – 600 °F |
| PIAT | 225 °C / 440 °F | 220 – 235 °C / 435 – 445 °F |
| Mold External Surface Temperature | 245 °C / 475 °F | 240 – 260 °C / 465 – 500 °F |
| Rotation | Similar to LMDPE. | |
| Oven Time | About 10 % more than LMDPE — 1 minute per 0.25 mm (0.01 inch) of wall thickness. | |
| Cooling | Delay airflow onto mold for about 5 minutes after removing from oven. Then fan‑air cool. | |
| Demould | Crystallizes at about 125 °C / 255 °F. Can be removed anywhere below 115°C / 240°F. Handle hot materials cautiously (see MSDS). Optimisation of the molded part may take up to 72 hours after demoulding due to continued crystallisation. | |
| Shrinkage | Approx. 1.5 % (1.5 – 2.5 %) — roughly 1 % less than LMDPE. | |
| Supervents | Known to improve processing and product appearance. laplastecnica.co.nz/products | |
