Polyvinyl Chloride PVC is composed of repeating units of vinyl chloride (CH2=CHCl), which polymerize to form a long-chain polymer. The polymerization process results in the formation of a chlorine atom (Cl) on the polymer chain, giving PVC its characteristic chlorine content. It is a rigid or flexible material depending on the specific formulation and is known for its excellent durability, chemical resistance, & flame retardant properties. It has a wide range of applications across various industries. Polyvinyl Chloride PVC is commonly used in construction for pipes, fittings, siding, window profiles, & roofing membranes.
