Application:
The program-controlled laboratory blown film extruder blown film means that the plastic melt is continuously extruded through the die under a certain temperature and a certain shearing force, and is inflated by compressed air, air ring cooling and frequency conversion traction. The process of obtaining a bi-fold plastic film. This machine is mainly used to detect the blown film feasibility of polymer materials and the gel condition in the material, as well as the dispersion of colored dispersion, control mixture and extrudate.
