1. Temperature Setting of Extruder:
| Zone | 1# | 2# | 3# | 4# | Head | Feeding 、Water Cooling 、Screw |
| Temp. | 140℃ | 150℃ | 155℃ | 160℃ | 165℃ | 65℃ |
2. It's recommended to use stainless steel wire filter(20×40×20).
3. The above temperature setting are the most typical ones. With different extruder devices, it can be adjusted in terms of the practical situation after extrusion in use, combining with melting pressure and current, in order to achieve the best extrusion result.
4. After a lone storage period the material needs to be dried before use.
