Coperion delivers new twin screw extruder to PolyOne


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).

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 ...
