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). 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, signage, inflatable products, and many applications where it replaces rubber.

PVC is used extensively in sewage pipe due to its low cost, chemical resistance and ease of jointing

PVC's relatively low cost, biological and chemical resistance and workability have resulted in it being used for a wide variety of applications. It is used for sewerage pipes and other pipe applications where cost or vulnerability to corrosion limit the use of metal. With the addition of impact modifiers and stabilizers, it has become a popular material for window and door frames. By adding plasticizers, it can become flexible enough to be used in cabling applications as a wire insulator. It has been used in many other applications. In 2013, about 39.3 million tonnes of PVC were consumed worldwide. PVC demand is forecast to increase at an average annual rate of 3.2% until 2021.

Product Description

Before PVC can be made into products, it has to be mixed with a range of additives. The essential additives for all PVC materials are heat stabilizers and lubricants. In the case of flexible PVC, plasticizers are also the main additives. Other additives, which may be used, include fillers, processing aids, impact modifiers and pigments. Additives will influence or determine the mechanical properties, light and thermal stability, color, clarity and electrical properties of the product. Once the additives have been selected, they are mixed with the polymer in a process called compounding

Application

Polyvinyl chloride (PVC) has the widest range of applications of any of the plastic polymers. PVC products can be colored, opaque, rigid, or flexible.
Rigid PVC compounds can be used in applications such as wall claddings, pipes, window & door profiles, pipe's fittings, cable tray and rolling shutters.
Flexible PVC compounds can also be used in applications, like shoes, seals, cable insulation, filling, and sheathing.
