What is formula for wire PVC?

The formula for polyvinyl chloride (PVC), commonly used for wire insulation, is (C2H3Cl)n, where "n" indicates the number of repeating units in the polymer chain. PVC is made through the polymerization of vinyl chloride monomers (C2H3Cl). It is valued for its durability, chemical resistance, and electrical insulation properties, making it a popular choice for electrical wiring applications.
