Laboratory blown film machine/instrument type BD-8878-A

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 inflation, air ring cooling, and variable frequency traction.Laboratory blown film machine/instrument type BD-8878-AMainly used to test the feasibility of blown film of polymer materials and the gel condition inside the materials, as well as the dispersibility of colored dispersions, control mixtures, and extrusions.
