PVCproduktion
PVC production, also known as polyvinyl chloride production, is the industrial process of manufacturing PVC resin. This versatile plastic is made through a series of chemical reactions. The primary raw materials are ethylene, typically derived from petroleum or natural gas, and chlorine, obtained from the electrolysis of brine (saltwater).
The first step involves the production of ethylene dichloride (EDC) through a process called direct chlorination
The final stage is the polymerization of VCM into PVC. This is typically achieved through suspension polymerization,
