Polymer’s Processing Additives Masterbatch ( PPA MB )
Product Description:
|
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
