Xplore Micro-Compounder

The Xplore Micro-Compounder is designed to address the most frequent and difficult problems encountered by the material scientist; limited quantities, abrasive materials, corrosive materials, highly filled materials, efficient mixing of nano-particles, and rapid turnaround. The barrel and screws are made of proprietary materials using a powdered metal process. The advantage is not only that the researcher can efficiently mix and process abrasive materials at extreme pH and high temperatures, he can use fast and aggressive cleaning techniques to dramatically reduce the cycle time and increase the throughput. High power heaters and liquid cooling provide rapid heating and cooling to further reduce cycle time. The Xplore Vari-Batch option offers the ability to efficiently mix quantities down to 2 cm3 using the 5 cm3 version of the Micro-Compounder and down to 3 cm3 using the 15 cm3 version. In addition to operating in the batch mode, the recycle valve can be left in the open position, a continuous feed hopper added and the Micro-Compounder can be used in a continuous mode as a conventional twin screw extruder.
