PVC Modification Method

PVC generally needs to be modified and granulated first. After the particles are prepared by the screw extruder, the plasticization will be more sufficient and the processing will be easier. Screw extruder is one of the main equipments for processing plastic molding, it through the external power delivery and external heating element plastic heat transfer of solid conveying, compaction, melting, shear mixing extrusion molding. No matter as plasticizing extruder granulation machinery or forming strictly, occupies an important position has special requirements of PVC products, PVC modified formula, is tailored according to customer requirements. There are also copolymerized derivatives in the production of PVC, such modified varieties as vinyl chloride copolymer, polyvinyl chloride blend and chlorinated polyvinyl chloride.
