LargeUse for: PE、LDPE、LLDPE、Blown film PP、masterbatch, filled masterbatch, plastics additives, functional masterbatch and so on，This lab film blowing machine is suitable to use one kg plastic granule to blow film, its a necessary equipment for machine testing, laboratory working. It can be used for blowing 30-200mm width PE film, which is good for making small plastic bags, packing film, etc.
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 for blown film material feasibility and gum condition is detected within the polymeric material, and a colored dispersion control mixture extrudate dispersion.
A.The machine mainly use for
1) laboratory research universities aggregate new polymer materials, material modification by
2) higher vocational schools teaching special
3) masterbatch production enterprises, separation of testing their products, plastics experiment with
4) plastic additives manufacturers, test its performance experiment
5) Large blown film plant, specializing in playing board
6) masterbatch sales company, its customers to play with color swatch
7) Functional Masterbatch manufacturer, test their products masterbatches experimental performance (for example: a conductive masterbatch)
B. function of the machine
1, blown film material modification test
2, blown film, blown film masterbatch to test "separation" and "plastics"
