Description and Uses

Polyvinyl chloride, commonly abbreviated PVC, is the thirdmost widely produced plastic, after polyethylene and polypropylene. PVC is used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. 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 clothing and upholstery, electrical cable insulation, inflatable products and many applications in which it replaces rubber.

Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol, but slightly soluble in tetrahydrofuran.

Poly(vinyl chloride), softened with a plasticizer such as esters, is used for making vinyl leather (used for handbags, briefcases, and inexpensive shoes), plastic raincoats, shower curtains, garden hoses, floor covering, and automobile upholstery.
