Blister packaging machine blister PVC modified granulation

PVC generally needs to be modified and granulated first. After being prepared into granules with a screw extruder, the plasticization is more sufficient and the processing is easier, especially for products that are injection-molded. Screw extruder is one of the most important equipment for plastic molding processing. It carries out solid conveying, compacting, melting, shearing, mixing and extrusion molding of plastics through external power transmission and heat transfer from external heating elements. The screw extruder plays an important role as a plasticizing granulation machine or a molding processing machine. Strictly speaking, PVC products with special requirements and PVC modified formula are tailored according to customer requirements. There are also copolymerization derivatives in the PVC production process. Such modified varieties include vinyl chloride copolymers, polyvinyl chloride blends and chlorinated polyvinyl chloride.
