Polyvinyl chloride is a widely used synthetic material that is used in many applications. Moreover, it is important to understand the production process of PVC for professionals in different fields. Because, it provides valuable insights into its production and applications. The production process of PVC involves in several key steps. It begins with obtaining Vinyl Chloride Monomer (VCM) through the chlorination of ethylene and pyrolysis of ethylene dichloride. After that, the polymerization of VCM leads to the creation of PVC, which has a glass transition temperature of 70-80°C. There are two main methods for commercial PVC production. Which are S-PVC and E-PVC processes. Both methods have their advantages and disadvantages for different applications. S-PVC is favored for flexible PVC formulations, while E-PVC is more cost-effective for specific uses.
