IDEAL PLATFORM PROCESSING SUPERIOR ENGINEERING PLASTICS


THE


FOR KEY POINTS FOR ENGINEERING PLASTICS PROCESSING


 Can include extruder from 18mm to140mm in size  High volume screws with low shear attributes and a Do/Di of 1.5 or more is preferable


 Feed materials are usually of a high bulk density  Compounding energy requirements vary significantly


depending on the melt viscosity of the base resin and the content of reinforcements


 Line configuration may be horizontal or vertical depending on manufacture volumes


 Reinforcements are frequently added downstream, though filler levels are light to moderate.


 A typical process section for engineering thermoplastics is 36D-40D in length.


RECOMMENDATIONS FOR ENGINEERED PLASTICS Shear rate Low Bulk density/Specific gravity Specific energy 0.5 / 0.9 g/cm 3 0.2-0.3 kwh/kg Horizontal/Vertical setup


Depends upon the output of the extruder. Up to 800 horizontal setup is preferred and above 1000kg/hr vertical setup is preferred


100% premix or split feed Both can be adopted


% of loading 5 to 50%


L/D of the machine 0:36-0:40
