During the extrusion process, CESA-process masterbatches coat the inner surface of the die, reducing the friction between the melt and the metal, allowing polymers to extrude more easily. By lowering the friction and eliminating or reducing melt-fracture and die buildup, CESA-process enables difficult-to-process materials such as narrow-molecular-weight LLDPE and LLDPE=rich blends to run on existing extrusion lines.
An example is CESA-process AEH603, a masterbatch based on fluoroelastomers. Developed for LLDPE and metallocene film extrusion, it can be used in conjunction with high quantities of fillers, antiblocking agents and inorganic pigments. In addition to eliminating melt-fracture and reducing die buildup, the use of this masterbatch enhances the optical properties of the film by improving its transparency. |
