LR-045 Лабораторна машина для видувної плівки
LR-045 Лабораторна машина для видувної плівки Use for: PE、LDPE、LLDPE、masterbatch, filled masterbatch, plastics additives, functional masterbatch and so on. This mini film blowing machine is suitable to use for laboratory working. Extrusion blown film refers to the plastic melt at a certain temperature, a certain shear force is continuously extruded through a die, blown by compressed air, air cooling and frequency pulling ring obtained double-folding plastic film process. This machine is mainly used to detect the feasibility of blowing film for polymer materials, as well as the dispersion of pigments and masterbatches.
