pc 203-22
pc resin is a polar non crystalline polymer, density: 1.380 g/cm3, glass transition temperature: 87 degrees c, so the thermal stability is poor, not easy to process. can not be used directly, must be modified mixing, adding related additives and filler can be used. it is determined that the properties and requirements of the prepared pvc materials are different because of the different kinds and fractions of the additive and filler. we usually call it a pvc formula, which is strictly a pvc modified formula, and pvc is only modified to use. this class is often classified as polymer modified material. the modification of polymer materials mainly revolves around the high performance of general plastics, the conversion of single component materials to multi component materials and composites, and the functionalization and optimization of materials. in general, pvc should be modified to granulate first, and after the formation of particles by screw extruder, the plasticization is more sufficient and the processing is easier, especially the process is the injection product. the screw extruder is one of the most important equipments in plastic molding. it is used for solid conveying, compaction, melting, shearing and mixing extrusion of plastics through external power transmission and heat transfer of external heating elements. screw extruders play an important role no matter as plasticizing and granulating machines or molding machines. strictly speaking, there are special requirements for pvc products. pvc modified formula is made according to customer requirements. there are also copolymerization in the pvc production process, such as vinyl chloride copolymers, pvc blends, and chlorinated polyvinyl chloride (pvc) [3].
