Parameter/Guideline
Drying
90-110°C / 3-5 hours (Mandatory and thorough, TPU is highly hygroscopic and prone to hydrolysis)
Melt Temperature
180 - 220 °C
Mold Temperature
20 - 40 °C
Critical Precautions
1. Drying is Critical: Any moisture causes melt degradation, leading to bubbles, splay marks, and severe strength loss.
2. Narrow Processing Window: Strictly control temperature to avoid overheating or prolonged residence time.
3. Potential Mold Sticking: Mold release agents may be needed for complex parts.Purge Suggestion
Purge thoroughly with ABS or HIPS at the lower end of the processing temperature range. Avoid using PP or PE.
