Emulsion and suspension polymerization process is substantially similar to PVC plastic profiles, only to be used a lot more of an emulsifier, and is not soluble in water but soluble in the monomer. Such polymerization system can effectively prevent the aggregation of polymer particles, thereby obtaining a small particle size polymeric resins, latex particle size generally produced PVC resin is 0.1-0.2mm rigid PVC plastic material, suspension of 20- 200mm. Initiator system and suspension polymerization are different, usually containing persulfate redox systems. The drying method is also designed to maintain a smaller particle diameter mode, often using some spray-drying agent. Since it is impossible to completely remove the emulsifier, and therefore the resins produced by emulsion can not be used for the production of articles that require high transparency, such as packaging films or require very low water-absorbing articles such as wire insulation. Emulsion PVC resin is generally higher than the price of suspension polymerization of resin, but the ingredients in liquid form requires the user to use such a resin, such as a paste resin. In the United States most of the resin emulsion products are paste resin (also known as dispersion resin), a small amount for latex. In Europe, a variety of emulsion technology is also used in the production of PVC plastic profiles universal resin manufacturers, especially rolling and extrusion resin. PVC is made by the polymerization of vinyl chloride monomer, is one of the commonly used thermoplastics. Its trade names referred to as "chlorine plastic", the abbreviation for PVC. Pure PVC resin is hard thermoplastic material PVC plastic profiles, its decomposition temperature and plasticizing temperature is very close, and poor mechanical strength. Therefore, you can not use products made of PVC plastic resin must be added plasticizers, stabilizers, fillers, etc. in order to improve performance, made of PVC, and then processed into various products. PVC, based on the amount of the plasticizer added much into rigid PVC and soft PVC. PVC plastic profile processing, PVC plastic profiles, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd.
