1.What is PVC?
Polyvinyl chloride plastics are polymerized from vinyl chloride monomers and are one of the commonly used thermoplastics. Its trade name is referred to as “chlorine plastic”, and the English abbreviation is PVC. Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticization temperature, and its mechanical strength is poor. Therefore, it is not possible to use polyvinyl chloride resin to make products. It is necessary to add plasticizers, stabilizers, fillers, etc. to improve performance, make polyvinyl chloride plastics, and then process them into various products. Polyvinyl chloride is divided into rigid polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added.
2.How PVC is processed through twin screw extruder?
PVC generally needs to be modified granulation firstly. After being made into particles by twin screw extruder, it will be plasticized and processed more easily , especially for injection-molded products. Plastic extruder is one of the most important equipment for plastic molding processing, it adopts external power transfer and heat transfer of external heating elements to carry out solid transport, compaction, melting, shear mixing and extrusion. Twin screw extruder plays an important role both for pelletizing machine and a molding processing machine. Technically , PVC products with special requirements and PVC modified formulations can be customized based on customers’ request.
