PVC resin SG8 with the K Value of 55-59 is mainly used for bottles, sheets, calendaring, rigid injection and moulding pipes. Most important, this model of PVC resin has high apparent density, good oil absorption and excellent plasticizing properties.

What Are The Main Application Fields of PVC Resin SG8

Average degree of polymerization of SG8 PVC resin is between 650 and 750. What’s more, it has the characteristics of low melting and gelation temperature, short plasticizing time and good fluidity. So it can be processed with little or no plasticizer.

The plastic products produced by PVC resin k57 usually have high transparency. They are suitable for using in the fields of records, profiles, home appliance shells, food packaging, and substitute plexiglass products. In short, PVC SG8 has good application prospects.

About the Production Process of PVC Resin SG8

The production of SG8 PVC resin generally adopts two processes. They are high temperature process without chain transfer agent and process with chain transfer agent. In general, SG-8 PVC resin produced by the process without transfer agent has relatively good particle size. If PVC SG8 is produced by high temperature method, the polymerization temperature is 67 °C. When the temperature is too high, the dispersant can’t be used normally. Temperature is too high means when the temperature exceeds the cloud point.

Adding chain transfer agent will improve the thermal stability of the resin product. However, the chain transfer agent has an impact on the dispersion system. And it is prone to produce coarse materials. Therefore, our company decided to optimize the selection of dispersant.

Now we use a suitable quaternary dispersion system to produce PVC resin SG8. It is high temperature process without adding chain transfer agent. We mainly carry out technological innovation and transformation through three aspects. One is to increase the production capacity of PVC resin K57. And it is achieved by shortening the polymerization batch and auxiliary time. The second is to improve product quality, and then strive to achieve sanitary standards. The third is to extend the cleaning cycle, and transform the original 108m³ polymerization reactor production process. Through continuous technological transformation, factory can produce sanitary grade SG8 polyvinyl chloride. Meanwhile, the rate of high-quality products has been significantly improved.
