As far as CPVC is concerned, even at the temperature of viscous flow (such as 195~205°C), its flow unit is still the primary particle, the interaction between fine resin particles is poor, the heat transfer effect is poor, and it is easy to produce melt fracture and plastic. poor quality. ACR is a processing aid that promotes plasticization. It can be dispersed in CPVC melt into network structure units with a size of less than 0.01um and evenly distributed among CPVC fine particles. Under the action of shear force, CPVC particles can be enlarged. The friction between them can promote the heat and mass transfer of the molten system, increase the torque, speed up the plasticization process, and improve the plasticization quality.
