Polyvinyl chloride (PVC) is the world's third most widely used plastic and is an attractive alternative to traditional materials such as glass, metal, wood, and other plastic materials because of its versatility, durability, and cost competitiveness. PVC can be tailored by adding modifiers (e.g., plasticizers, stabilizers) to achieve specific properties, categorized into rigid PVC (uPVC) and flexible PVC, making it suitable for diverse industrial and consumer applications.
