Description
Physical Foaming Insulation Materials Mixed With Activators is a kind of high molecular weight polyolefin, processing temperature, on the basis of the the typical for appropriate adjustments
Please refer to the following processing conditions when using.
(L/D=32:1~38:1):
First zone | Second zone | Third zone | Forth zone | Fifth zong | Sixth zone | Die head | Die mouth | Screw speed(r/m) |
158℃ | 172℃ | 188℃ | 198℃ | 205℃ | 195℃ | 178℃ | 165℃ | 26—32 |
The above table is for reference only, the actual processing temperature should be based on the technical parameters of the extruder,through the gentle adjustment and practical operation to set.
In order to prevent the increase of the bubble hole in the extruder, the melting section should maintain the appropriate pressure, if the pressure is not enough, there will be large gaps and holes. The selection of the screen, the die core and the die sleeve are all the factors that influence the melt pressure.
