Permanent Virtual Circuit (PVC) A permanent virtual circuit (PVC) is a connection that is permanently established between two or more nodes in frame relay and asynchronous transfer mode (ATM) based networks. It enables the creation of a logical connection on top of a physical connection between nodes that communicate frequently or continuously.
PVC has become widely used in clothing, to either create a leather-like material or at times simply for the effect of PVC. PVC clothing is common in Goth, Punk, clothing fetish and alternative fashions. PVC is less expensive than rubber, leather, and latex which it is therefore used to simulate.n extensive market for chlorinated PVC is in pipe for use in office building, apartment and condominium fire protection. CPVC, as it is called, is produced by chlorination of aqueous solution of suspension PVC particles followed by exposure to UV light which initiates the free-radical chlorination.
