PPA Masterbatch

PPA Masterbatch can be used to improve the processing performance of all types of polyolefins, including LLDPE, LDPE, HDPE and PP by extrusion process.
Polymers melt fracture is generally the surface imperfection seen as a regular surface with ridges running perpendicular to the extrusion direction especially in films, which is also known as �Shark Skin Effect�
Recommendations for masterbatch Preparation should not have PPA content above 5% since this can lead to poor dispersion. A level around 2% is desirable. The table below can be used to determine the percentage of masteratch to be included in the final mixture to obtain the required level in PPM
Following Benefits in final product:
� Elimination of Melt fracture (shark skin)
� Improvement of production Higher Output
� Improvement of film transparency
� Improvement of smoothness and surface aspect
� Improvement of product appearance
� Improvement of mechanical properties
� Reduction of gels
� Reduced Power Consumption
� Increasing screw torque
� Maintenance time reduction
� Reduction of die build-up
� Consistency of production
� Smoother extrusion conditions
� Lower energy consumption
� Reduction of cycle times and quicker transition
� Reduction of potential negative interaction with other film additives such as anti-block and HALS
� Reduction of extruder torque
� Reduction of polymer critical shear rate
