Processing Guideline Extrusion
Cylinder Temperature 160 - 180 - 200 °C, max. 250 °C (320 - 360 - 390 °F; max. 480 °F)
Screw Geometry Standard three-zone screw (e.g. polyolefin screw). The screw must be able to provide sufficient shearing.
L/D Ratio At least 25
Compression Ratio At least 3.5 : 1
Screens / Breaker Plate A breaker plate and a screen pack are generally recommended in the extruder configuration in order to increase pressure.
Die Land <= 3 mm ( <= 0,12 in.)
Extruder Head Ca. 200 °C (390 °F)
Die Temperature Ca. 200 - 230 °C (390 - 450 °F)
Predrying Pre drying of the material is not necessary; if surface moisture forms as a result of changes in temperature, the material should be dried for 2 - 4 hours at 60 - 80 °C (140 - 175 °F). To avoid porosity in the profile a pre drying is recommended for wall thickness > 3mm.
Calibration Generally not necessary; support elements may be required when extruding THERMOLAST® compounds with high hardness or when coextruding with standard thermoplastics.
Cleaning Recommendation For cleaning and purging of the machine it is appropriate to use polypropylene or polyethylene. Machine must be PVC-free.
