| Processing Guide: | TPE - Thermoplastic Elastomers |
|
|
| Extruder: |
Single screw extruder with vacuum pressure-relieved grooved feeding section (by increased screw pitch and channel depth) |
|
|
| Screw Design: |
Barrier screw, 25 - 30 L/D Two mixing sections: dispersive-mixing spiral-shear element, rhomboid distributive-mixing section |
|
|
| Compression Ratio: | 3,5:1 |
|
|
| Cylinder Temperatures: |
150-185 C 302-365 F |
|
|
| Melt Temperature: |
175-200 C 347-392 F |
|
|
| Pre-Drying: |
no, but 2 hours at 80 C (176 F) if extreme temperature change |
|
|
| Calibration: |
no, but supporting inner pressure if hollow profiles |
|
|
| Miscellaneous: | Breaker plate/screens for higher back pressure and therefore smoother profile surface |
