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.

Pure polyvinyl chloride is a white, brittle solid generally delivered as powder or pellets. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.

PVC is manufactured from petroleum. The production process also uses sodium chloride. Recycled PVC is broken down into powder or small chips with the impurities removed. The resulting product is refined to make pure white PVC. It can be recycled approximately seven times. Its lifespan is about 140 years.
