PolyOne Europe has ordered the new ZSK 26 Mc18 twin screw extruder from Coperion GmbH, for the company's trials in the development of its fiber reinforced and additive-enhanced polymers. Coperion will supply the equipped laboratory extruder from start to finish: from the material feeding system (Coperion K-Tron) to the compounding extruder to the pelletizing system (Coperion pelletizing technology).
Twin screw extruders from Coperion are already in service at several PolyOne production sites. For the new laboratory extruder, PolyOne decided in favor of a version with specific wear-resistant barrels and screw elements. The ZSK 26 Mc18, which features a 25 mm screw diameter, has been specially designed for the development of formulations and the production of samples. With output rates of up to 180 kg/hour the extruder is also suitable for the compounding of small batches.
The ZSK 26 Mc18 for PolyOne is equipped with a ZS-B side feeder for the introduction of fillers and additives and a ZS-EG side devolatilization, both of which are mounted directly on the side of the machine with the aid of a specially developed swing arm. The laboratory extruder includes four Coperion K-Tron loss-in-weight feeders for solid materials and one liquid loss-in- weight feeder. The loss-in-weight feeders are equipped with patented SFT weighing technology and operate with accuracy due to their reported high speed, high resolution performance ...
