This equipment is a test equipment developed by our company according to the customized requirements of various research and development institutions and colleges and universities. Environmental protection foaming agent such as supercritical CO2 can be used to continuously extrude physical foaming materials such as PLA/PP/PA/PET/PBAT to produce sheet and sheet products. The weightless mixing system is used for automatic feeding and mixing, which has a high degree of automation and stable continuous extrusion foaming. The double screw extruder can also be used to replace the granulation mold and modify the formula of various materials
