Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the 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 for bottles, other non-food packaging, and cards (such as bank or membership cards).
PVC extrusions are specially-designed shapes made of PVC by a plastic extruder. PVC is an abbreviation for polyvinyl chloride, which is a synthetic polymer. There are many kinds of synthetic polymers, and many of them are plastics like PVC. The defining characteristic of PVC is its versatility.
