FAQ
Why is PCL hard to extrude?
PCL has a low melting point (~60°C) and narrow processing window. It degrades easily when overheated, causing molecular weight loss and poor mechanical properties. Precise temperature control and low-shear screw designs are essential.
PCL has a low melting point (~60°C) and narrow processing window. It degrades easily when overheated, causing molecular weight loss and poor mechanical properties. Precise temperature control and low-shear screw designs are essential.
Use precise temperature control, minimize shear heating, and avoid long residence time. Drying resin before processing and using CO₂ as a processing aid can also reduce degradation significantly.
Which extruder is best for PCL sheet?
Parallel twin-screw extruders are preferred for better mixing, precise temperature control, and energy efficiency at high outputs. They handle PCL’s temperature sensitivity better than conical or single-screw designs.
