产品用途

Extrusion film blowing refers to the technological process that the double-folded plastic film made by compressed air huffing, vane cooling and frequency conversion traction and the plastic melt being extruded through dies at a certain temperature and certain cutting force. This machine is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials, as well as the dispersibility of colored dispersion,controlled mixture and extrudate.
