Give the properties and application of PVC.
Polyvinylchloride (PVC): It is replacing rubber to a great extent in veracious applications. There is PVC insulated (non-sheathed) or PVC insulated and sheathed cables for general reason wiring is now well established and the option between VIR and PVC is very frequently largely a issue of relative price or personal preference on the part of the user. An attractive feature of it is that this can be produced in clear and permanent color describing identifications where many of single core cable have to be used. All cables with PVC insulation are not influenced by oils and petrol and thus used in factories and wireraft.
