What is Polyvinyl Chloride (PVC)?
Polyvinyl chloride (PVC) is a synthetic polymer of vinyl chloride. It is the third-most widely produced plastics globally, with diverse applications ranging from pipes and fittings to flooring and medical devices. PVC’s versatility is due to its ability to be formulated in different ways, including rigid and flexible forms.
Polyvinyl Chloride (PVC) Chemical Formula
The chemical formula of polyvinyl chloride (PVC) is (C₂H₃Cl)n, where n represents the number of repeating units in the polymer chain. This formula signifies that PVC is composed of vinyl chloride monomers polymerized to form long chains.
