Extrude Foamed Wood Composites Without Drying.
The new system increases the volume of melt exposed to devolatilizing by using screws with deeper roots for longer residence time. The system has 34:1 L/D, including both sections, but devolatilizes as effectively as a 42:1 conventional extruder, Coronado says. It can extrude foamed or unfoamed wood-filled PVC, PP, and PE at rates up to 1200 lb/hr.
