Introduction and main role of plastic processing aid

plastic processing aid is a substance play a supporting role, generally have a filter aid, clarification, adsorption, lubrication, stripping, bleaching, peeling, solvent extraction, fermentation with nutrients like. Some for food, some used in manufacturing, and so on. PVC Processing aid  a very special thermoplastic resin processing its pure decomposition, poor mobility, low impact strength, poor weather, and therefore need to add all kinds of supplementary material in the process to improve its performance. plastic processing aid according to the different Processing aid  weight, there are different functions. The main role of plastic processing aid are: to accelerate the process of PVC plastics; improve the rheological properties of the thermoplastic melt; improve the mechanical properties of the melt under the heat elastic state; despite add less plastic processing aid, but to improve the processing performance but PVC is very important. Pure PVC impact due to poor performance, particularly low-temperature impact performance is poor, poor weather, the application is limited in many areas. Therefore, the need to improve the impact modifier added to its toughness and weatherability.
