Polyvinyl Chloride (PVC) is a widely used synthetic plastic polymer structured around a backbone of carbon atoms. In the PVC structure, each carbon atom alternates with a chlorine atom. The formula for its repeating unit can be depicted as -[CH2-CHCl]-n, showcasing the vinyl groups (ethene molecule) with one hydrogen replaced by a chlorine atom. This structure gives PVC its distinct properties such as durability, resistance to environmental degradation, and versatility in applications. PVC can be made softer and more flexible by the addition of plasticizers. Its rigid form is used in construction for pipes and in profiles, whereas the flexible form is used in applications such as electrical cable insulation, inflatable products, and many applications where it replaces rubber. PVC’s unique molecular structure is key to its utility across various industries, combining economic and mechanical value with relatively straightforward production processes.
