PVC
Polyvinyl chloride is the world's third-most widely produced synthetic polymer of plastic. About 40 million tons of PVC are produced each year.
PVC comes in two basic forms: rigid 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 plastic bottles, non-food packaging, food-covering sheets, and plastic 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. Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.
