Polyvinyl Chloride (PVC) is one of the most widely produced thermoplastic polymers in the world after polyethylene and polypropylene. Without the additions of plasticizers, PVC is a naturally white, brittle plastic. Its most common use is in the construction industry, but it is also used to manufacture signs, in healthcare applications, and as a fiber for clothing.
PVC is primarily produced as a rigid or unplasticized polymer (RPVC) or as a flexible plastic (uPVC). Flexible, plasticized or regular PVC is softer and more amenable to bending than uPVC due to the addition of plasticizers like phthalates such as diisononyl phthalate or DINP. Flexible PVC is commonly used in construction as insulation on electrical wires or in flooring for homes, hospitals, schools, and other areas where a sterile environment is necessary. Rigid PVC is also used in construction as pipe for
PVC is produced in rigid and flexible forms to support a broad range of end uses. Rigid, or unplasticized PVC, is commonly used in construction applications such as pipe and siding and often referred to as vinyl in the United States. Flexible PVC incorporates plasticizers and is used where increased flexibility is required.
Flexible PVC is commonly used in construction as insulation on electrical wires or in flooring for homes, hospitals, schools, and other environments where durability and cleanability are required. Rigid PVC is also used for bottles, non-food packaging, and cards, including credit or membership cards. Additional applications include imitation leather, signage, phonograph records, inflatable products, and uses where PVC replaces rubber.
Pure polyvinyl chloride is typically supplied as a white, brittle solid in powder or pellet form. It is insoluble in alcohol and slightly soluble in tetrahydrofuran.
PVC is manufactured from petroleum, with sodium chloride used in the production process. Recycled PVC is broken down into powder or small chips with impurities removed and refined into reusable material. It can be recycled approximately seven times with a lifespan of about 140 years.
