TPE - Thermoplastic Elastomers

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/DTwo 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
