PTH two-stage extruder,the ideal compounding and pelletizing system for processing of heat and shear sensitive materials. PTH two-stage extruder is mainly designed for the modification and compounding of heat and shear sensitive materials. Its two-stage set-up and the modular principle of the process section allow highly efficient compounding of applications such as PVC, XLPE and HFFR cable compounds, soft PVC, medical compounds, EVA footwear compounds, etc. High torque design allows to use smaller size of twin screw to achieve expected output, which will help to save space and energy consumption.
