The new Brabender Basic Line from C.W. Brabender, S. Hackensack. N.J., is based on a 16-mm twin-screw extruder for basic laboratory-scale formulation development within a small footprint. The system combines adaptability of processing lengths with easy cleaning and handling via a segmented clamshell barrel and segmented screws. It can produce samples using only a small amount (100 g) of raw material. In the near future, 18- and 25-mm sizes will also be available.
The line can be transformed from a compounding system to one for extruding blown or cast film simply by exchanging the dies and docking module for the new processes. Software for these additional processes is already integrated within the PLC controls.
This system is offered as a complete compounding line, which includes the extruder, PLC control, touchscreen panel, closed-loop water chiller, segmented barrel with screws (L/D based on processing needs), double-strand die, strand cooling tank with wiper, and a fixed-length pelletizer. The extruder with PLC controls, feeder, and die are in a single table module, and the strand cooling tank with pelletizer are on a second table module that docks to the first.
