Farrel Corp. said its new CP125, the latest model of its CP Series II, was developed for small-scale compounding in a laboratory, a pilot plant or limited production.
Its throughput rate is between 176-330 pounds an hour.
Farrel said the CP125 is good at running polyolefin-based compounds with high levels of mineral fillers, additives and color masterbatches; polymer-rubber blends; and applications that need high-intensity mixing at a low processing temperature.
The twin-screw extruder has counterrotating, nonintermeshing rotors, which Farrel said allows for fast color changes. The CP125 comes standard with a single-stage extruder. A two-stage vented barrel also is available.
Ansonia, Conn.-based Farrel recently installed a CP125 in its laboratory in Rochdale, England. Customers can test their specific materials on the line, which includes gravimetric feeders for metering test materials to the continuous mixer and extruder. The line can be fitted with either a strand die or an underwater pelletizing system.
