Two Stage Extruder for PVC Compound And High Filler Masterbatch
Product Description
The two stage extruder ：The first stage twin extruder usually runs at the high speed for better compounding and higher throughput. The second stage must be a single screw extruder, with a large diameter and low speed operation. The low screw speed avoids over-shearing force, Due to the strong heat exchange ability ,the internal cooling system can effectively prevent overheating . The two stage extruder allows the operator to perform more flexible , predictable mixing processes and temperature control.
The two stage extruder is mainly used for the compounding of thermoplastic and shearing . double-stage structure are suitable for processing a variety of materials, such as: PVC, XLPE cable material, soft PVC medical material, hard PVC, EVA foam sole material, PE low smoke no Halogen resistance fuel, etc.
