PPA/Additives: Interaction Studies
As a professional in PE formulation, you probably encounter some issues in term of interactions between PPA and additives.
-
Resin producers usually use only one feeding zone for all the additives and the extrusion temperature is high. These two parameters increase the interactions between the additives.
-
Masterbatch producers use separate feeder for the additives and lower extrusion temperature, this is the reason why there is less interactions.
Make sure to discuss with the company about understanding the behavior of PPA when extruded in a PE formulation or masterbatch formulation to help you select the best blending method in your formulation and maintain your product's performance.
