BD-8878-A Laboratory Film Blowing Machine/Instrument Type
Extrusion blown film refers to the process of continuously extruding a plastic melt through a die at a certain temperature and shear force, and obtaining a double folded plastic film through compressed air blowing, air ring cooling, and variable frequency traction. This machine is mainly used to detect the feasibility of blown film of polymer materials and the gum condition inside the materials, as well as the dispersibility of colored dispersions, control mixtures, and extrusions.
