Polyvinyl chloride polyvinyl ( PVC) is the world’s third-most widely produced synthetic plastic polymer (after polyethylene and polypropylene PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows.
It is also used in making bottles, non-food packaging, food-covering sheets, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber. With cotton or linen, it is used in the production of canvas.
Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran
POLYVINYL CHLORIDE (PVC) Products
PVC is popular across several applications due to its flexibility, durability, sustainability and being a vital element in effective water management. PVC is not only used in piping systems, but also in wider applications such as windows and kitchens
PVC is a thermoplastic polymer. Its properties are usually categorized based on rigid and flexible .
