Parallet co-rotating twin screw extruders have excellent mixing performance, good self cleaning performance and flexible modular configuration characteristics which make them suitable for processing different types of material systems, and are extensively used in fields of polymer processing, foodstuff processing and chemical products, especially for various high molecular materials.

In most cases, parallet co-ratating twin screw extruders are used as mixing equipments in processing high molecular materials, the modification process and master batch preparation of polyolefin materials and engineering plastics require sufficient and intensive mixing, which difference depending on material systems. Excellent equipmet performance, reasonable mixing process, advanced combination technique and rich processing experience are the key factors determining the success and efficiency of mixing.
